Not many vendors offer diamond grading laboratory reports (aka gemstone quality reports) for their customers. My overall advice for you is to keep your cash in your pocket when coping with these kinds of jewelers.
Just buy a diamond engagement ring when it includes the initial diamond quality record.
A laboratory report is an independent test of the 4Cs of a loose pearl and contains a plotted diagram of the rock’s clarity characteristics plus a picture representation of the rock’s proportions. Having such a record lets you compare diamonds of unique qualities and finally makes it possible to create a more educated purchasing decision.
A merchant may cut corners rather than supply a laboratory report or a unscrupulous seller may offer a fake one due to the time, cost and trouble he will bear for a rock rated.
Yeah – there’s a cost for grading a diamond (though that price is finally covered by the customer), in addition to the insurance and shipping fees for sending the diamond into the laboratory. And don’t overlook the opportunity cost of a shopper not getting the diamond from his shop available for a couple of weeks while the grading occurs GSI vs GIA.
But a diamond grading report might likewise not be accessible because the prices to getting one can influence too heavily on the last cost of the ring.
By way of instance, a 0.3ct diamond ring costing250 state, may cost approximately $75 to be rated and also have the report number inscribed on the girdle on the diamond.
As you hunt for that perfect diamond engagement ring to your love, you are going to discover that there’s an alphabet soup of labs asserting to supply reliable diamond grading reports. I, however, would just put my money…
The Premier Diamond Grading Lab Reports
Yes, most of diamond quality reports aren’t made equal. Within the business, it’s a consensus that both greatest labs are GIA-GTL (Gemological Institute of America’s Gem Trade Laboratory) and the AGS (American Gem Society Laboratories).
The GCAL (Gem Certification and Assurance Lab) additionally offers highly recognized reports or “diamond certificates” as they’re known by GCAL.
The GIA has got the most powerful international reputation for consistency and independence. On account of their continuous colour and clarity strictness guidelines, the globe’s biggest and most expensive diamonds are shipped there for scoring decades. In 2006, GIA-GTL included a two-dimensional cut grading system for round brilliant diamonds.
AGS employs the strictest cut criteria in the business. It utilizes a three-dimensional lighting performance metric which may grade several diamond contours. In reality, it’s the sole cut grading system that’s recognized by the scientific community.
Furthermore, its Diamond Quality Document employs a unique and proprietary 0 10 grading method to assess the 4 Cs – a platform that is much easier to understand than GIA’s grading method. In reality, AGS goes the excess step by equating their 010 score scale to other sorts of evaluation.
