Diamond 4C

Not all sellers offer diamond grading science lab reports to their shoppers. therefore my general recommendation to you is to stay your cash in your pocket once handling such jewelers.

Only purchase a diamond ring if it comes with the first diamond quality report.

A science lab report is associate freelance analysis of the 鑽石4c and includes a planned diagram of the stone’s clarity characteristics and a graphic illustration of the stone’s proportions. Having such a report permits you to match diamonds of various qualities and ultimately helps you create a a lot of abreast of shopping for call.

A merchandiser could perform associated not offer a science lab report or an unscrupulous merchandiser could offer a faux one due to the time, bother and expense he’ll bear to obtaining a stone stratified.

Yeah – there’s a value for grading a diamond (though that value is eventually paid by the consumer), and the shipping and insurance charges for causation the diamond to the science lab. And allow us to not forget the chance value of a jeweler not having the diamond in his store purchasable for a couple of weeks whereas the grading takes place.

However, a diamond grading report may additionally not be accessible as a result of to obtaining one could impact too heavily on the ultimate price of the ring.

For example, a 0.3ct diamond ring cost accounting $250 say, could value around $75 to be stratified and have the report variety inscribed on the girdle on the diamond.

As you look for that ideal diamond ring for your sweetheart, you will find that there’s associate alphabet soup of labs claiming to supply reputable diamond grading reports. however I’d solely place my cash on…

The Premier Diamond Grading science lab Reports

Yes, all diamond quality reports aren’t created equal. among the business, it’s an agreement that the 2 premier labs area unit GIA-GTL (Gemological Institute of America’s Gem Trade Lab) and therefore the AGS (American Gem Society Laboratories).

The GCAL (Gem Certification and Assurance Lab) additionally offers extremely regarded reports or “diamond certificates” as they’re said by GCAL.

The Armed Islamic Group has the strongest world name for independence and consistency. because of their constant color and clarity strictness tips, the globe’s largest and costliest diamonds are sent there for grading decades. In 2006, GIA-GTL accessorial a two-dimensional cut grading system for spherical sensible diamonds.

AGS uses the strictest cut standards within the business. It uses a three-dimensional light-weight performance metric which will grade many diamond shapes. In fact, it’s the sole cut grading system that’s recognized by the scientific community.

What is a lot of, its Diamond Quality Document uses a novel and proprietary zero to ten grading system to gauge the four Cs – a system that is less complicated to grasp than GIA’s grading system. In fact, AGS even goes the additional step by equalization their 0-10 rating scale to alternative sorts of rating.

For example, the traditional VS1 diamond clarity rating could be a three on the AGS Diamond Quality Document.
