Not all sellers offer diamond grading lab stories (aka diamond quality reviews) to their consumers. So my general advice to you is to maintain your income in your pocket when working with such jewelers.
Only obtain a diamond engagement ring if it arrives with the first diamond quality report.
A lab report is an independent analysis of the 4Cs of a free diamond and involves a plotted diagram of the stone’s clarity traits and a graphic illustration of the stone’s proportions. Possessing this kind of a report allows you to assess diamonds of various traits and in the long run aids you make a a lot more informed getting decision.
A retailer could lower corners and not give a lab report or an unscrupulous seller could offer a bogus one because of the time, problems and cost he’ll bear to receiving a stone graded.
Yeah – there is a cost for grading a diamond (though that expense is at some point compensated by the client), plus the shipping and insurance policy costs for sending the diamond to the lab. And let us not forget the prospect value of a jeweler not possessing the diamond in his shop for sale for a number of weeks even though the grading requires area.
Nonetheless, a diamond grading report may also not be obtainable due to the fact the expenses to receiving 1 may affect as well heavily on the ultimate price tag of the ring.
For case in point, a .3ct diamond ring costing $250 say, might value close to $seventy five to be graded and have the report number inscribed on the girdle on the diamond.
As you research for that perfect diamond engagement ring for your sweetheart, you’ll discover that there is an alphabet soup of labs declaring to offer respected diamond grading reviews. But I would only set my cash on…
The Premier Diamond Grading Lab Studies
Indeed, all diamond top quality studies are not developed equivalent. In the business, 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 hugely regarded studies or “diamond certificates” as they are referred to by GCAL.
The GIA has the strongest global track record for independence and consistency. Thanks to their constant color and clarity strictness suggestions, the globe’s greatest and most pricey diamonds have been sent there for grading a long time. In 2006, GIA-GTL included a two-dimensional reduce grading technique for round excellent diamonds.
AGS employs the strictest lower specifications in the business. It employs a a few-dimensional light functionality metric that can grade several diamond styles. In reality, it is the only minimize grading method that is acknowledged by the scientific group.
What is far more, its Diamond Quality Document employs a exclusive and proprietary to ten grading program to consider the 4 Cs – a technique which is less difficult to comprehend than GIA’s grading system. In simple fact, AGS even goes the added action by equating their -ten ranking scale to other kinds of rating.
For instance, the traditional VS1 diamond clarity score is a 3 on the AGS Diamond Top quality Doc.
Diamond Reporting – The Disadvantages
one. Diamond grading is not standardized or controlled and therefore you may appear across tier 2 labs that use looser suggestions to the tier one grading labs described earlier mentioned.
If you buy a diamond that has been graded by a tier 2 lab, you could finish up having to pay much more for a lesser good quality diamond. So for illustration, a diamond rated a “F” in shade at a tier two lab may get a G, H, or reduced coloration score at a far more reliable lab.
The sector also discounts diamonds graded by lesser known labs by about fifteen-30% or far more. So either you only buy a diamond graded by a tier one lab or you acknowledge that you may well be getting a lesser high quality diamond than what is stated on the report if that diamond is graded by a lesser known lab.
2. Several large chain shops have large contracts with lesser identified labs with “softer” diamond grading tips. 鑽石gia of these softer labs set “recommended replacement values” on the lab studies – values which are increased than what retailers intends sell the diamonds for.
So a salesperson in a chain retailer might say to you, “Search at the wonderful deal you are obtaining here. We are promoting you this diamond engagement ring for $2500 but the report claims that the proposed substitute worth is $4000.” Wow – what a offer – NOT! This is why it is far better that you have faith in only impartial tier one labs.
Also bear in head that reputable diamond grading reports are not appraisals and never supply appraisal figures. Diamond appraisals are typically grossly inflated and are not something you will want to count on.
three. Diamond reviews are riddled with disclaimers that specify that absolutely nothing is “certified” or confirmed and that the labs are not accountable for problems. In fact, the GIA offers a disclaimer of types on their internet site with regards to the use of the word “certify.” The web site says:
“It is incorrect to condition that college students, graduates, their businesses, or particular gemstones are “certified” by GIA. The Gemological Institute of America does not certify any person or anything. Neither a scholar nor a graduate who has been awarded a certificate or diploma, nor a gem which has been graded or recognized by GIA has been certified by GIA”.
So it is attainable that you the consumer is left keeping the bag ought to an inaccuracy in a report is later identified. Courts have frequently ruled that sellers, not labs, are dependable for this kind of mistakes. Why? Because the labs indicated beforehand that their studies couldn’t be held liable.
Thankfully, there are a pair techniques to give oneself far more purchaser safety:
A. You could fly to India in which jewelers provide a lifetime buyback policy to their customers. Too expensive to fly?
B. You could locate one particular of the 20% of US jewelers who market totally bonded diamonds. These are diamonds that are offered with lifetime breakage, lifetime trade-in and life span buyback insurance policies.
C. Not as very good a treatment as acquiring a fully bonded diamond but you could buy a diamond that arrives with an genuine “certificate” and not a report. “Certified diamonds do appear with guaranties” albeit for shorter durations.October 7, 2019
