Not all sellers supply diamond grading lab studies (aka diamond quality reports) to their buyers. So my standard advice to you is to keep your cash in your pocket when dealing with such jewelers.
Only purchase a diamond engagement ring if it will come with the unique diamond high quality report.
A lab report is an impartial analysis of the 4Cs of a unfastened diamond and consists of a plotted diagram of the stone’s clarity qualities and a graphic representation of the stone’s proportions. Getting this sort of a report makes it possible for you to compare diamonds of various characteristics and in the long run aids you make a a lot more educated getting determination.
A retailer could lower corners and not offer a lab report or an unscrupulous vendor could offer a faux 1 because of the time, trouble and expenditure he’ll bear to getting a stone graded.
Yeah – there is a value for grading a diamond (however that price is ultimately compensated by the buyer), in addition the shipping and delivery and insurance policy costs for sending the diamond to the lab. And let us not neglect the possibility expense of a jeweler not obtaining the diamond in his retailer for sale for a handful of weeks although the grading will take spot.
Nonetheless, a diamond grading report might also not be offered since the expenses to getting a single could impact as well greatly on the ultimate value of the ring.
For instance, a .3ct diamond ring costing $250 say, could cost all around $75 to be graded and have the report variety inscribed on the girdle on the diamond.
As you search for that perfect diamond engagement ring for your sweetheart, you will uncover that there is an alphabet soup of labs professing to offer respected diamond grading reports. But I would only place my funds on…
The Premier Diamond Grading Lab Stories
Yes, all diamond top quality stories are not produced equivalent. Inside the industry, it is a consensus that the two premier 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 gives very regarded reports or “diamond certificates” as they are referred to by GCAL.
The GIA has the strongest international popularity for independence and regularity. Thanks to their consistent shade and clarity strictness recommendations, the globe’s largest and most costly diamonds have been sent there for grading decades. In 2006, GIA-GTL extra a two-dimensional cut grading method for spherical outstanding diamonds.
AGS employs the strictest lower expectations in the business. It employs a 3-dimensional gentle efficiency metric that can grade several diamond shapes. In fact, it is the only cut grading system that is recognized by the scientific community.
What is a lot more, its Diamond Top quality Doc uses a special and proprietary to 10 grading system to appraise the 4 Cs – a system which is less complicated to understand than GIA’s grading system. In reality, AGS even goes the further phase by equating their -ten rating scale to other forms of score.
For case in point, the standard VS1 diamond clarity score is a three on the AGS Diamond Good quality Doc.
Diamond Reporting – The Downsides
1. Diamond grading is not standardized or controlled and hence you might come across tier 2 labs that make use of looser recommendations to the tier 1 grading labs talked about earlier mentioned.
If you get a diamond that has been graded by a tier two lab, you may possibly end up paying out more for a lesser high quality diamond. So for example, a diamond rated a “F” in coloration at a tier two lab could get a G, H, or decrease coloration score at a a lot more reputable lab.
The sector also special discounts diamonds graded by lesser recognized labs by about fifteen-thirty% or more. So both you only acquire a diamond graded by a tier one lab or you accept that you might be acquiring a lesser quality diamond than what is said on the report if that diamond is graded by a lesser acknowledged lab.
two. Many big chain retailers have enormous contracts with lesser recognized labs with “softer” diamond grading suggestions. 鑽石購買 of these softer labs set “suggested alternative values” on the lab reviews – values which are increased than what retailers intends promote the diamonds for.
So a salesperson in a chain retailer could say to you, “Search at the great offer you are acquiring right here. We are promoting you this diamond engagement ring for $2500 but the report claims that the recommended alternative value is $4000.” Wow – what a offer – NOT! This is why it is much better that you have confidence in only independent tier one labs.
Also bear in brain that reliable diamond grading stories are not appraisals and never offer appraisal figures. Diamond appraisals are often grossly inflated and are not something you are going to want to count on.
three. Diamond studies are riddled with disclaimers that specify that nothing is “qualified” or assured and that the labs are not accountable for glitches. In fact, the GIA gives a disclaimer of kinds on their web site concerning the use of the term “certify.” The internet site claims:
“It is incorrect to condition that pupils, graduates, their firms, or particular gemstones are “certified” by GIA. The Gemological Institute of The us does not certify anyone or anything. Neither a student nor a graduate who has been awarded a certification or diploma, nor a gem which has been graded or identified by GIA has been accredited by GIA”.
So it is feasible that you the client is left keeping the bag must an inaccuracy in a report is later uncovered. Courts have regularly dominated that sellers, not labs, are accountable for such mistakes. Why? Simply because the labs indicated beforehand that their reviews couldn’t be held liable.
The good news is, there are a few methods to give yourself much more customer protection:
A. You could fly to India where jewelers offer you a life span buyback policy to their buyers. As well expensive to fly?
B. You could locate a single of the 20% of US jewelers who market totally bonded diamonds. These are diamonds that are offered with life span breakage, life time trade-in and lifetime buyback policies.
C. Not as excellent a remedy as getting a totally bonded diamond but you could buy a diamond that comes with an genuine “certificate” and not a report. “Qualified diamonds do arrive with guaranties” albeit for shorter durations.
