Not all sellers offer diamond grading lab reviews (aka diamond good quality stories) to their consumers. So my common tips to you is to hold your money in your pocket when working with this sort of jewelers.
Only buy a diamond engagement ring if it arrives with the original diamond good quality report.
A lab report is an unbiased evaluation of the 4Cs of a loose diamond and consists of a plotted diagram of the stone’s clarity traits and a graphic representation of the stone’s proportions. Possessing these kinds of a report permits you to compare diamonds of different qualities and in the end helps you make a a lot more informed buying decision.
A retailer could cut corners and not provide a lab report or an unscrupulous seller might provide a fake one simply because of the time, difficulty and expenditure he’ll bear to getting a stone graded.
Yeah – there is a price tag for grading a diamond (though that expense is sooner or later compensated by the customer), in addition the shipping and delivery and insurance expenses for sending the diamond to the lab. And let us not neglect the possibility price of a jeweler not getting the diamond in his keep for sale for a number of months while the grading normally takes location.
Nonetheless, a diamond grading report could also not be obtainable because the charges to obtaining one may possibly affect way too heavily on the final price tag of the ring.
For case in point, a .3ct diamond ring costing $250 say, may expense about $75 to be graded and have the report quantity inscribed on the girdle on the diamond.
As you search for that ideal diamond engagement ring for your sweetheart, you’ll uncover that there is an alphabet soup of labs professing to provide trustworthy diamond grading reports. But I would only set my funds on…
The Premier Diamond Grading Lab Studies
Of course, all diamond quality reports are not produced equal. In the industry, it is a consensus that the two leading labs are GIA-GTL (Gemological Institute of America’s Gem Trade Lab) and the AGS (American Gem Culture Laboratories).
The GCAL (Gem Certification and Assurance Lab) also delivers extremely regarded studies or “diamond certificates” as they are referred to by GCAL.
The GIA has the strongest worldwide track record for independence and consistency. Because of to their constant colour and clarity strictness guidelines, the globe’s greatest and most high-priced diamonds have been sent there for grading decades. In 2006, GIA-GTL added a two-dimensional lower grading method for round amazing diamonds.
AGS makes use of the strictest reduce expectations in the business. It uses a three-dimensional mild overall performance metric that can grade many diamond designs. In fact, it is the only reduce grading system that is identified by the scientific neighborhood.
What is much more, its Diamond Quality Document uses a distinctive and proprietary to ten grading technique to consider the 4 Cs – a system which is less complicated to understand than GIA’s grading program. In fact, AGS even goes the added step by equating their -ten rating scale to other types of ranking.
For case in point, the conventional VS1 diamond clarity score is a three on the AGS Diamond High quality Document.
Diamond Reporting – The Downsides
1. Diamond grading is not standardized or controlled and hence you might arrive throughout tier 2 labs that utilize looser suggestions to the tier 1 grading labs mentioned previously mentioned.
If you buy a diamond that has been graded by a tier 2 lab, you may possibly stop up paying out much more for a lesser top quality diamond. So for instance, a diamond rated a “F” in color at a tier 2 lab may possibly get a G, H, or decrease colour rating at a more reliable lab.
The market also discount rates diamonds graded by lesser acknowledged labs by about 15-30% or a lot more. So either you only purchase a diamond graded by a tier 1 lab or you acknowledge that you may well be getting a lesser good quality diamond than what is stated on the report if that diamond is graded by a lesser acknowledged lab.
two. Several large chain stores have enormous contracts with lesser acknowledged labs with “softer” diamond grading tips. Some of these softer labs set “proposed replacement values” on the lab reviews – values which are larger than what merchants intends offer the diamonds for.
So a salesperson in a chain shop may possibly say to you, “Seem at the excellent deal you are acquiring listed here. We are promoting you this diamond engagement ring for $2500 but the report suggests that the advised alternative price is $4000.” Wow – what a deal – NOT! This is why it is greater that you believe in only independent tier 1 labs.
Also bear in mind that trustworthy diamond grading stories are not appraisals and will not offer you appraisal figures. Diamond appraisals are often grossly inflated and are not something you’ll want to depend on.
3. Diamond stories are riddled with disclaimers that specify that practically nothing is “licensed” or certain and that the labs are not accountable for errors. In truth, the GIA offers a disclaimer of kinds on their site with regards to the use of the word “certify.” The internet site suggests:
“It is incorrect to state that learners, graduates, their organizations, or certain gemstones are “licensed” by GIA. 鑽石4c of America does not certify any individual or anything. Neither a college student nor a graduate who has been awarded a certification or diploma, nor a gem which has been graded or determined by GIA has been certified by GIA”.
So it is attainable that you the customer is still left holding the bag should an inaccuracy in a report is afterwards identified. Courts have often ruled that sellers, not labs, are responsible for these kinds of mistakes. Why? Since the labs indicated beforehand that their reports could not be held liable.
Luckily, there are a couple ways to give your self more purchaser defense:
A. You could fly to India where jewelers supply a life time buyback plan to their consumers. As well pricey to fly?
B. You could uncover one of the twenty% of US jewelers who promote fully bonded diamonds. These are diamonds that are marketed with lifetime breakage, life time trade-in and life time buyback guidelines.
C. Not as very good a treatment as purchasing a entirely bonded diamond but you could purchase a diamond that arrives with an real “certificate” and not a report. “Accredited diamonds do come with guaranties” albeit for shorter durations.
