Enhanced Diamonds
Enhanced Diamonds
Many people are unaware that a number of techniques are used to improve the clarity of diamonds by removing or hiding imperfections.
Two very common techniques are laser drilling and fracture filling.
1st Laser Drilling
Many diamonds come from the earth with tiny black inclusions inside them. Even if they are hard to see, they tend to scatter light and reduce the brilliance of the diamond.
About 25 years ago, high powered laser beams were first used to "burn-out" these impurities.
To reach the inclusion, a laser drill is used to create a tiny hole reaching deep inside the diamond. Often the laser's heat will vaporize the speck. If not, acid is poured into the hole, usually dissolving the spot or bleaching it to a less noticeable white color.
Naturally, this process is irreversible. And, since it has become an "industry-standard" procedure, it's not usually disclosed by diamond sellers.
The holes are so small in diameter, it's very difficult to see that the diamond has been drilled. Still, looking at the side of the stone in very bright light may show some thin "threads." Diamond grading reports will usually indicate that a stone has been laser drilled.
The Federal Trade Commission has recently revised the "Trade Practice Guides for the jewelry industry, and surprisingly, has omitted laser drilling from its list of diamond treatments that should be disclosed to the public.
Normally, the FTC requires disclosure if the treatment: (1) is reversible (ie not permanent), (2) requires special care and handling (different from an untreated gem), and (3) substantially affects the diamond's value.
Laser drilling is permanent. However, drilled diamonds are less desirable and worth considerably less than undrilled ones of otherwise equal size and equal grade. Be sure to ask if you're buying the diamond has been laser drilled.
Hight & Randall, staff Jeweler, will not sell laser drilled diamonds.
2nd Fracture Filling
Sometimes, a chemical substance is used to fill small cracks in a diamond. The effect of this treatment can be very dramatic, turning a very "ugly" diamond into one that is remarkably brilliant.
However, all other things being equal, a treated, clarity-enhanced diamond is worth much less than one that is naturally beautiful. There's nothing inherently wrong with gem enhancement, as long as you know what's been done to the stone, and you're not paying for one thing and receiving another.
This makes it important to know how to detect fracture filling.
Luckily, the "refractive index" of filler material is different from a diamond. It's close, but different enough so that you can detect its presence by rotating the diamond under a bright light. At certain angles, the filler will create a "flash effect."
It is important to note that, if a fracture filled diamond is submitted to extreme heat (such as that used with a jeweler's torch for prong ring sizing or repairs), the filling material may bleed out of the diamond, thus leaving the formerly masked inclusion Visible. Two companies in the United States supply most of the fracture-filled diamonds sold They are working to ensure that their products are not misrepresented to consumers, and both indicate that fracture filling may be redone if necessary.
However, there are reports of thousands of fracture-filled diamonds (especially small ones) being surreptitiously released into the jewelry distribution channel. You must be extra-vigilant when the true source of the diamond being shown to you is unknown.
Hight & Randall will never sell fracture filled diamonds.
3rd Other Enhancement Techniques
There are various chemical coatings that can be used on a diamond to temporarily enhance its color.
Radiation treatments can be applied to off-colored diamonds, turning low-value brownish yellow stones into expensive fancy colored diamonds (pinks, greens, blues, etc.). This is not fraud as long as it is disclosed. However, this treatment is difficult to detect except by a gem lab, and often, the diamonds are misrepresented as natural.
Hight & Randall, staff Jeweler, will never sell irradiated diamonds.
4th Fraudulent and Unethical Practices
One tip-off is a price that's too good to be true. The actual value of a real unenhanced, natural diamond is something that can be determined rather precisely. Since a diamond's value depends upon each of the "4C's," there are nearly 2800 combinations for different quality diamonds. Therefore, there are 2800 different possible prices for, say, a one carat diamond.
Some stores use fictitious discounts to make it appear that you're buying a diamond for less than its true value. They mark up the item, then use a "sale" theme to attract customers with a discount. " It is important for you to know that anyone in business must make a profit, in order to offer the services and products their customers expect, and to remain in business.
One myth that has existed for years is, "the markup on jewelry is high." Those offering constant "sales" and big markdowns are hoping the public still believes this fable.
The truth is, according to a recent industry accounting report, "The Cost of Doing Business Survey," the jeweler's average profit after expenses is less than 5%. Most jewelers want to offer good value at a competitive price, but real markdowns of 25% to 60% would not allow stores to stay in business.
Be wary of discounted prices. If the price seems too good to be true, it probably is.
Unless you are a diamond expert, you can never be certain about the identification or quality of a stone. That is why it's a good idea to buy your diamond from a reliable, recognized professional jewelry, such as a Certified Gemologist or Certified Gemologist Appraiser of the American Gem Society (AGS), or a Graduate Gemologist of the Gemological Institute of America (GIA) . These credentials are your assurance that the jeweler has been properly trained. (The AGS is the only jewelry industry institution that confers upon titles and "certifies" its members. AGS also requires annual retesting and recertification of its members.)
(a) Concealing Flaws in Mounting.
Although there's nothing wrong with covering a flaw by proper placement under a prong or bezel or some other setting, doing so for the purpose of misrepresenting the quality of the stone is not acceptable.
(b) Misleading Information Regarding Diamond Reports
You should know that according to various independent laboratories will issue diamond grading reports, for a fee. These laboratories do not buy or sell diamonds, but simply provide independent opinions of a diamond's identity and quality. (Most laboratories do not appraise diamonds, that is, apply a dollar value to them.) The best-known laboratories include the GIA Gem Trade Laboratory, European Gem Laboratory (EGL), the American Gem Society (AGS), and the Diamond High Council of Belgium (HRD). The International Gem Institute (IGI) also issues grading reports, as well as what many consider to be inflated appraisal reports. The seller tells IGI what the appraisal amount on the report is to be. Exaggerated appraisals benefit only the seller, leading the buyer to believe that the diamond is worth more than it actually is.
Grading reports are often mistakenly offered to the public as "certificates" or "certs." The seller might say, "This is a certed GIA diamond," implying that GIA is guaranteeing the grade. If you read the fine print and disclaimers on these reports, you'll see that the diamond grading labs do not certify anything. They simply indicate the grader's opinion as to the quality of the diamond being graded. Therefore, a grading report is not a guarantee or certificate of quality. Only your jeweler can guarantee or certify the quality of the diamond you select.
Some sellers will imply that diamonds with grading reports are of better quality than diamonds without grading reports. The truth is, that all independent grading labs will accept any and all diamonds submitted for grading. This means that poorly cut as well as ideal cut diamonds, diamonds and all in between, may have grading reports. It is important for you to know what the information on the grading report means.
(c) Falsely or upgrading old ring Grading Reports
While not a common practice, some will change the information on the grading report to make the diamond appear more valuable than it really is, they've even used counterfeit reports.
(d) Exaggerated or split Grading
When a diamond is not accompanied by a grading report, some unscrupulous sellers will represent the stone in an "overly optimistic" fashion with regard to color and clarity grades. This practice is often referred to as "wish grading. . . "I wish it a G color." (but it's really an I.)
Still others use noncommittal split grading "when asked about the quality of a given diamond. They may say, "Oh, this is an H / I, SI diamond." Well, which is it? Is it SI1 H or H SI2, or is it I SI1 or I SI2? This nondescript method of grading can mean differences of hundreds or even thousands of dollars in price, depending on the 4C's of the particular diamond in question. If the exact diamond grade can not be determined by the seller, do not buy the stone!
At Hight & Randall, staff Jeweler, every diamond's carat weight, cut, color, and clarity are unconditionally guaranteed in writing.
(e) "Appraising" jewelry that the store sold
This common but unethical practice causes problems for the jeweler, as well as their customer. Let's say you buy a new diamond ring, which is tagged at $ 4000 For whatever reason, the jeweler is willing to sell it to you for $ 2500th The jeweler then gives you a jewelry appraisal document, stating the replacement value to be $ 4000
If the ring has just been purchased for $ 2500 it can be replaced for $ 2500th Legally, an appraisal is an opinion of current market conditions. The current market for the ring is $ 2500, not $ 4000
The jeweler appraising his own merchandise for more than you paid is fibbing to you, and potentially to your insurance company as well. If you use the fictitiously high appraisal to insure your jewelry, you will also pay higher insurance premiums.
Instead, your jeweler should offer an "estimate to replace." This document, if properly done, will be accepted by your insurance company, and wi Enhanced Diamonds

Sometimes a chemical substance used to small cracks in a diamond. The effect of this treatment can be very dramatic, from a very "ugly" diamond in a remarkable is that brilliant.
But all other things equal, handled, clarity-enhanced diamond is worth much less than a course that is beautiful. There is nothing wrong inherently with jewel improvement, as long as you know, what has been done to the stone, and you're not paying for one thing and receiving another.
It is therefore important to know how to recognize fracture filling.
Fortunately, the refractive index "filler material differs from a diamond. It is a close, but different enough so that you can recognize their presence by turning the diamond under a bright light. At certain angles, the filler will be a "flash" effect.
It is important to note that if a fraction filled diamond is submitted to extreme heat (such as that used with a jeweller's torch for ring sizing pen or repairs), the filler May bleed from the diamond, so that the formerly masked inclusion visible . Two companies in the United States provide most of the fracture-filled diamonds sold. They work to ensure that their products are not misrepresented to consumers, and both pointed out that fracture filling can be renewed.
However, there are reports of thousands of fracture-filled diamonds (especially young), secretly in the jewellery sales channel. You have to be extra vigilant if the true source of diamonds will be shown, is not known.
Hight & Randall will never sell diamonds fracture filled.

Some stores use fictitious discounts seem to make the point that you purchase a diamond for less than their actual value. They mark the position, then use a "sale" issue to attract customers with a "discount". It is important for you to know that someone in the business must make a profit, so that services and products their customers expect, and to remain in business.
A myth, there have been years, "the markup on jewelry is high." This offering constant "sales" and large discounts are hoping the public still believe that this fable.
The truth is, according to a recent report from the accounting industry, "The Cost of Doing Business Survey, the average jeweller's profit after costs of less than 5%. Most jewelers want to offer good value at a competitive price, but real price reductions of 25% to 60% would not allow shops to stay in business.
Be wary of reduced prices. If the price seems too good to be true, it is likely.
Unless you are a diamond expert, you can never be sure about the identification or the quality of a stone. Therefore it is a good idea to buy your diamonds from a reliable and recognised professional jewelry, such as a certified Gemologist or Certified Gemologist Appraiser of the American Gem Society (AGS), or a Graduate Gemologist of the Gemological Institute of America (GIA). These credentials are your assurance that the jeweler was properly trained. (The AGS is the only institution jewelry industry, and gives title to "certify" its members. AGS also an annual retesting and recertification of its members.)
(a) concealing deficits in the assembly.
Although there's nothing wrong, an error by the appropriate placement under a pen or bezel, or any other setting, so for the purpose of misrepresenting the quality of the stone is not acceptable.
(b) Misleading information on Diamond reports
You should know that several independent laboratories diamond jewelry piece is grading reports, for a fee. These laboratories do not buy or sell diamonds, but only an independent opinions of a diamond's identity and quality. (Most laboratories not judge, diamonds, that is, a dollar value to them.) Among the best known are the laboratories GIA Gem Trade Laboratory, European Gem Laboratory (EGL), the American Gem Society (AGS) and the Diamond High Council by Belgium (HRD). The International Gem Institute (IGI) also questions the classification of reports, as well as what many as inflated appraisal reports. The seller tells IGI, what the amount of the assessment in his report. Exaggerated reports only benefit the seller, the buyer to believe that the diamond is worth more than it actually is.
Grading reports are often mistakenly offered to the public as "certificates" or "Zert." The seller might say: "This is a concerted GIA Diamond", which means that GIA is to ensure the quality. If the fine print and disclaimers in these reports, you will see that the diamond-grading laboratory can not confirm. They simply give the students with the opinion about the quality of the diamonds is graded. It is a classification report is not a guarantee or a certificate of quality. Only your jeweler can guarantee or certify the quality of the diamonds you select.
Some sellers will mean that the classification of diamonds reports are of better quality than diamonds without grading reports. The truth is that all independent laboratories classification accept all the diamonds for grading. This means that badly cut and ideal cut diamonds, diamonds and all in between could have grading reports. It is important for you to know what the information on the classification report says.
(c) Incorrect update or change grading reports
While not common practice, some of the information on the classification report to the diamonds apparently worth more than it really is, they have even falsified reports.
(d) Exaggerated or Split Grading
If a diamond is not a classification report, some unscrupulous sellers, the stone in an "overly optimistic" fashion in terms of color and clarity grades. This practice is often referred to as "wish classification. . . "I wish her a G color." (but it really is a I.)
Still others use non-binding "split rating" on the question of the quality of a particular diamond. You can say: "Oh, this is an H / I, SI Diamond." Well, is it? Is it SI1 H or H SI2, or is it I SI1 and SI2 I? This senseless method of classification may mean differences of hundreds or even thousands of dollars in price, depending on the 4C's of particular diamonds in question. If the exact diamond class can not be determined by the seller, not buy the stone!
In height & Randall, Personal Jeweler, each Diamond's carat weight, cut, color and clarity are unconditionally guaranteed in writing.
(e) "test" jewellery, that the business sells
These common, but unethical practice causes problems for the jeweller, as well as their customers. Let's say you buy a new diamond ring, which is marked at $ 4000 For whatever reason, the jeweler is willing to sell you for $ 2500. The jeweller, then gives you a jewelry appraisal document, stating the replacement value to $ 4000
If the ring has just been purchased for $ 2500 it can be replaced for $ 2500. Legally, an appraisal is an opinion of the current market conditions. Given the current market situation for the ring is $ 2500, $ 4000.
The jeweller to assess its own goods for more than you paid for fibbing to you, and possibly to your insurance company as well. If the fictitious high valuation to insure your jewelry, you pay higher insurance premiums.

(a) concealing deficits in the assembly.
Although there's nothing wrong, an error by the appropriate placement under a pen or bezel, or any other setting, so for the purpose of misrepresenting the quality of the stone is not acceptable.
(b) Misleading information on Diamond reports
You should know that several independent laboratories diamond jewelry piece is grading reports, for a fee. These laboratories do not buy or sell diamonds, but only an independent opinions of a diamond's identity and quality. (Most laboratories not judge, diamonds, that is, a dollar value to them.) Among the best known are the laboratories GIA Gem Trade Laboratory, European Gem Laboratory (EGL), the American Gem Society (AGS) and the Diamond High Council by Belgium (HRD). The International Gem Institute (IGI) also questions the classification of reports, as well as what many as inflated appraisal reports. The seller tells IGI, what the amount of the assessment in his report. Exaggerated reports only benefit the seller, the buyer to believe that the diamond is worth more than it actually is.
Grading reports are often mistakenly offered to the public as "certificates" or "Zert." The seller might say: "This is a concerted GIA Diamond", which means that GIA is to ensure the quality. If the fine print and disclaimers in these reports, you will see that the diamond-grading laboratory can not confirm. They simply give the students with the opinion about the quality of the diamonds is graded. It is a classification report is not a guarantee or a certificate of quality. Only your jeweler can guarantee or certify the quality of the diamonds you select.
Some sellers will mean that the classification of diamonds reports are of better quality than diamonds without grading reports. The truth is that all independent laboratories classification accept all the diamonds for grading. This means that badly cut and ideal cut diamonds, diamonds and all in between could have grading reports. It is important for you to know what the information on the classification report says.
(c) Incorrect update or change grading reports
While not common practice, some of the information on the classification report to the diamonds apparently worth more than it really is, they have even falsified reports.
(d) Exaggerated or Split Grading
If a diamond is not a classification report, some unscrupulous sellers, the stone in an "overly optimistic" fashion in terms of color and clarity grades. This practice is often referred to as "wish classification. . . "I wish her a G color." (but it really is a I.)
Still others use non-binding "split rating" on the question of the quality of a particular diamond. You can say: "Oh, this is an H / I, SI Diamond." Well, is it? Is it SI1 H or H SI2, or is it I SI1 and SI2 I? This senseless method of classification may mean differences of hundreds or even thousands of dollars in price, depending on the 4C's of particular diamonds in question. If the exact diamond class can not be determined by the seller, not buy the stone!
In height & Randall, Personal Jeweler, each Diamond's carat weight, cut, color and clarity are unconditionally guaranteed in writing.
(e) "test" jewellery, that the business sells
These common, but unethical practice causes problems for the jeweller, as well as their customers. Let's say you buy a new diamond ring, which is marked at $ 4000 For whatever reason, the jeweler is willing to sell you for $ 2500. The jeweller, then gives you a jewelry appraisal document, stating the replacement value to $ 4000
If the ring has just been purchased for $ 2500 it can be replaced for $ 2500. Legally, an appraisal is an opinion of the current market conditions. Given the current market situation for the ring is $ 2500, $ 4000.
The jeweller to assess its own goods for more than you paid for fibbing to you, and possibly to your insurance company as well. If the fictitious high valuation to insure your jewelry, you pay higher insurance premiums.
