Not all sellers offer diamond grading lab reviews (aka diamond company satisfactory reports) to their consumers. So my popular recommendation to you is to preserve your cash to your pocket whilst dealing with such jewelers.
Only purchase a diamond engagement ring if it comes with the unique diamond nice report.
A lab file is an unbiased assessment of the 4Cs of a loose diamond and consists of a plotted diagram of the stone’s readability traits and a picture illustration of the stone’s proportions. Having this type of record lets in you to compare diamonds of various characteristics and ultimately allows you’re making a more informed buying selection.
A retailer may additionally cut corners and now not offer a lab report or an unscrupulous seller may additionally offer a fake one because of the time, trouble and cost he’ll endure to getting a stone graded.
Yeah – there may be a fee for grading a diamond (though that value is finally paid with the aid of the patron), plus the shipping and coverage expenses for sending the diamond to the lab. And allow us to now not forget about the opportunity cost of a jeweler no longer having the diamond in his store for sale for some weeks while the grading takes place.
However, a diamond grading document can also not be to be had due to the fact the costs to getting one may additionally effect too closely on the very last price of the ring.
For example, a zero.3ct diamond ring costing $250 say, may cost a little around $75 to be graded and have the report quantity inscribed on the girdle at the diamond.
As you look for that best diamond engagement ring for your sweetheart, you may find that there may be an alphabet soup of labs claiming to provide legit diamond grading reports. But I could handiest placed my money on…
The Premier Diamond Grading Lab Reports
Yes, all diamond high-quality reports are not created identical. Within the enterprise, it’s miles a consensus that the two greatest labs are GIA-GTL (Gemological Institute of America’s Gem Trade Lab) and the AGS (American Gem Society Laboratories).
The GCAL (Gem Certification and Assurance Lab) additionally offers surprisingly seemed reviews or “diamond certificate” as they are noted with the aid of GCAL.
The GIA has the strongest international recognition for independence and consistency. Due to their consistent colour and clarity strictness suggestions, the globe’s biggest and maximum high-priced diamonds have been sent there for grading decades. In 2006, GIA-GTL delivered a two-dimensional cut grading machine for spherical great diamonds.
AGS makes use of the strictest cut standards in the enterprise. It uses a 3-dimensional mild performance metric that may grade several diamond shapes. In reality, it is the most effective cut grading machine that is diagnosed by the clinical network.
What is more, its Diamond Quality Document uses a unique and proprietary zero to 10 grading system to evaluate the four Cs – a device which is easier to comprehend than GIA’s grading device. In fact, AGS even goes the greater step by equating their 0-10 rating scale to different kinds of rating.
For example, the conventional VS1 diamond readability rating is a three on the AGS Diamond Quality Document.
Diamond Reporting – The Drawbacks
1. Diamond grading is not standardized or regulated and as a result you may encounter tier 2 labs that rent looser hints to the tier 1 grading labs cited above.
If you buy a diamond that has been graded by using a tier 2 lab, you may turn out to be paying greater for a lesser best diamond. So as an example, a diamond rated a “F” in shade at a tier 2 lab may get a G, H, or lower coloration score at a extra authentic lab.
The enterprise additionally discounts diamonds graded with the aid of lesser known labs via approximately 15-30% or extra. So either you simplest buy a diamond graded with the aid of a tier 1 lab or you accept which you might be shopping for a lesser fine diamond than what is stated on the document if that diamond is graded by means of a lesser acknowledged lab.
2. Many big chain stores have huge contracts with lesser known labs with “softer” diamond grading suggestions. Some of these softer labs positioned “cautioned alternative values” on the lab reviews – values which might be better than what stores intends sell the diamonds for.
So a salesclerk in a series keep can also say to you, “Look at the extraordinary deal you are getting here. We are promoting you this diamond engagement ring for $2500 but the file says that the cautioned substitute price is $4000.” Wow – what a deal – NOT! This is why it’s miles better that you trust only independent tier 1 labs.
Also undergo in thoughts that respectable diamond grading reviews are not appraisals and don’t provide appraisal figures. Diamond appraisals are regularly grossly inflated and are not some thing you may want to rely upon.
3. Diamond reports are riddled with disclaimers that specify that not anything is “certified” or assured and that the labs are not liable for errors. In reality, the GIA offers a disclaimer of types on their internet site concerning the usage of the word “certify.” The internet site says:
“It is inaccurate to country that scholars, graduates, their agencies, or particular gemstones are “licensed” by means of GIA. The Gemological Institute of America does no longer certify everybody or anything. Neither a pupil nor a graduate who has been awarded a certificates or degree, nor a gem which has been graded or identified by means of GIA has been certified by using GIA”.
So it’s miles viable which you the client is left protecting the bag must an inaccuracy in a record is later discovered. Courts have frequently dominated that dealers, no longer labs, are liable for such mistakes. Why? Because the labs indicated beforehand that their reports couldn’t be held liable.
Fortunately, there are a couple methods to present your self greater customer protection:
A. You ought to fly to India where jewelers provide an entire life buyback coverage to their clients. Too high-priced to fly?
B. You may want to locate one of the 20% of US jewelers who promote completely bonded diamonds. These are diamonds which can be sold with lifetime breakage, lifetime change-in and lifelong buyback rules.
C. Not as top a remedy as shopping for a completely bonded diamond but you may buy a diamond that includes an real “certificates” and no longer a file. “Certified diamonds do include guaranties” albeit for shorter intervals.
Some sellers talk to a “diamond document” as a “licensed diamond” but technically this isn’t correct. From a prison perspective, a diamond document is a honestly an professional opinion though in reality, components of a diamond grading report aren’t simply evaluations.
For example, a diamond’s carat (weight) may be appropriately determined as well as its cut grade via measuring its optical performance or by way of referring to a laptop model. A certificate on the other hand is a announcement of reality – a report for which the issuer accepts felony responsibility and will make restitution to the patron for mistakes.
Some pinnacle diamond grading labs provide both reports and certificate. AGS gives Diamond Quality Documents (non-certified reports) and also Diamond Quality Certificates. Diamond Quality Certificates are prepared solely for AGS retail jewelers and offers guaranties from collaborating American Gem Society member shops.
GCAL certifies it is diamond grading also. Its a hundred% cash-back guarantee coverage is valid for a period of two years from the date at the applicable certificates. This policy ensures the accuracy of the reduce, colour and readability grades and the carat weight.
A file or certificates should will have quite a number on it that can or may not be inscribed on a diamond. You could be able to enter that range at the website of the certifying lab to check a file’s validity.
