The Premier Diamond Grading Lab Reports
Yes, all diamond pleasant reviews are not created equal. Within the industry, it’s far a consensus that the 2 most reliable 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) also offers rather regarded reviews or “diamond certificate” as they’re noted by using GCAL.
The GIA has the strongest global reputation for independence and consistency. Due to their constant colour and clarity strictness suggestions, the globe’s biggest and most pricey diamonds had been despatched there for grading a long time. In 2006, GIA-GTL added a -dimensional reduce grading gadget for round tremendous diamonds.
AGS makes use of the strictest reduce requirements in the industry. It uses a three-dimensional light performance metric that could grade numerous diamond shapes. In fact, it is the only reduce grading machine this is diagnosed through the medical community.
What is extra, its Diamond Quality Document uses a unique and proprietary 0 to 10 grading device to evaluate the 4 Cs – a system that’s easier to comprehend than GIA’s grading system. In fact, AGS even is going the extra step by using equating their zero-10 rating scale to different varieties of score.
For instance, the traditional 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 hence you can encounter tier 2 labs that employ looser guidelines to the tier 1 grading labs referred to above.
If you buy a diamond that has been graded by means of a tier 2 lab, you can come to be paying greater for a lesser exceptional diamond. So for example, a diamond rated a “F” in coloration at a tier 2 lab may additionally get a G, H, or decrease colour rating at a extra respectable lab.
The industry also reductions diamonds graded by lesser known labs by means of approximately 15-30% or greater. So either you best purchase a diamond graded via a tier 1 lab otherwise you be given which you is probably buying a lesser pleasant diamond than what’s said at the report if that diamond is graded by means of a lesser recognised lab.
2. Many massive chain shops have huge contracts with lesser known labs with “softer” diamond grading tips. Some of these softer labs placed “suggested replacement values” at the lab reports – values which are higher than what shops intends sell the diamonds for.
So a salesperson in a series store may additionally say to you, “Look on the first-rate deal you are getting here. We are promoting you this diamond engagement ring for $2500 but the file says that the counseled replacement cost is $4000.” Wow – what a deal – NOT! This is why it is better that you accept as true with handiest independent tier 1 labs.
Also undergo in thoughts that reliable diamond grading reviews aren’t appraisals and don’t offer appraisal figures. Diamond value determinations are often grossly inflated and are not some thing you’ll want to depend upon.
Three. Diamond reports are riddled with disclaimers that explain that not anything is “certified” or guaranteed and that the labs aren’t accountable for errors. In fact, the GIA gives a disclaimer of sorts on their website regarding using the word “certify.” The internet site says:
“It is incorrect to state that scholars, graduates, their corporations, or specific gemstones are “certified” through GIA. The Gemological Institute of America does not certify all people or some thing. Neither a pupil nor a graduate who has been awarded a certificates or diploma, nor a gem which has been graded or diagnosed by using GIA has been licensed through GIA”.
So it’s far possible which you the patron is left protecting the bag ought to an inaccuracy in a file is later found. Courts have regularly ruled that sellers, not labs, are responsible for such mistakes. Why? Because the labs indicated beforehand that their reports couldn’t be held responsible.
Fortunately, there are a couple methods to provide your self extra customer protection:
A. You should fly to India where jewelers offer a lifetime buyback coverage to their customers. Too costly to fly?
B. You should discover one of the 20% of US jewelers who sell fully bonded diamonds. These are diamonds which can be offered with lifetime breakage, lifetime alternate-in and lifelong buyback rules.
C. Not as excellent a remedy as buying a completely bonded diamond but you may buy a diamond that comes with an actual “certificates” and no longer a record. “Certified diamonds do come with guaranties” albeit for shorter periods.
Some sellers discuss with a “diamond record” as a “certified diamond” but technically this is not correct. From a legal standpoint, a diamond file is a simply an expert opinion though in reality, aspects of a diamond grading file aren’t simply critiques.
For example, a diamond’s carat (weight) may be appropriately determined in addition to its cut grade by measuring its optical performance or through regarding a pc version. A certificates alternatively is a declaration of truth – a file for which the provider accepts criminal obligation and could make restitution to the customer for mistakes.
Some pinnacle diamond grading labs offer each reviews and certificates. AGS offers Diamond Quality Documents (non-certified reports) and also Diamond Quality Certificates. Diamond Quality Certificates are prepared completely for AGS retail jewelers and gives guaranties from collaborating American Gem Society member shops.
GCAL certifies it is diamond grading additionally. Its a hundred% cash-back assure policy is legitimate for a period of two years from the date on the applicable certificates. This policy ensures the accuracy of the reduce, shade and clarity grades and the carat weight.
A file or certificate have to could have a variety of on it that can or may not be inscribed on a diamond. You may be capable of enter that variety on the internet site of the certifying lab to test a report’s validity.
