Read through The Diamond Grading Report Ahead of Purchasing An Engagement Ring

Not all sellers supply diamond grading lab reviews (aka diamond high quality stories) to their customers. So my standard tips to you is to preserve your funds in your pocket when working with these kinds of jewelers.

Only buy a diamond engagement ring if it arrives with the first diamond high quality report.

A lab report is an unbiased evaluation of the 4Cs of a unfastened diamond and involves a plotted diagram of the stone’s clarity characteristics and a graphic representation of the stone’s proportions. Possessing this kind of a report allows you to compare diamonds of various characteristics and ultimately assists you make a more informed getting selection.

A retailer may possibly lower corners and not provide a lab report or an unscrupulous seller could supply a fake 1 simply because of the time, trouble and expenditure he’ll bear to obtaining a stone graded.

Yeah – there is a price for grading a diamond (though that value is eventually compensated by the consumer), furthermore the shipping and delivery and insurance policy charges for sending the diamond to the lab. And let us not overlook the chance value of a jeweler not obtaining the diamond in his keep for sale for a couple of months whilst the grading requires place.

However, a diamond grading report could also not be available since the fees to obtaining one particular might affect too intensely on the final value of the ring.

For case in point, a .3ct diamond ring costing $250 say, might expense around $75 to be graded and have the report amount inscribed on the girdle on the diamond.

As lab grown diamond look for for that ideal diamond engagement ring for your sweetheart, you may locate that there is an alphabet soup of labs claiming to give reputable diamond grading reports. But I would only put my income on…

The Premier Diamond Grading Lab Stories

Indeed, all diamond quality reports are not developed equivalent. Inside the market, 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 Culture Laboratories).

The GCAL (Gem Certification and Assurance Lab) also offers highly regarded reports or “diamond certificates” as they are referred to by GCAL.

The GIA has the strongest worldwide status for independence and consistency. Due to their continuous colour and clarity strictness guidelines, the globe’s premier and most high-priced diamonds have been despatched there for grading many years. In 2006, GIA-GTL included a two-dimensional minimize grading program for round brilliant diamonds.

AGS employs the strictest minimize requirements in the business. It employs a 3-dimensional light efficiency metric that can quality many diamond styles. In reality, it is the only cut grading method that is acknowledged by the scientific group.

What is more, its Diamond High quality Document employs a distinctive and proprietary to 10 grading system to assess the 4 Cs – a system which is simpler to understand than GIA’s grading system. In reality, AGS even goes the extra action by equating their -10 ranking scale to other varieties of ranking.

For illustration, the typical VS1 diamond clarity rating is a three on the AGS Diamond High quality Doc.

Diamond Reporting – The Drawbacks

1. Diamond grading is not standardized or regulated and consequently you may possibly come across tier two labs that utilize looser recommendations to the tier 1 grading labs described previously mentioned.

If you get a diamond that has been graded by a tier 2 lab, you might stop up having to pay a lot more for a lesser good quality diamond. So for illustration, a diamond rated a “F” in color at a tier 2 lab might get a G, H, or reduced color ranking at a a lot more reliable lab.

The sector also discounts diamonds graded by lesser known labs by about fifteen-30% or much more. So both you only buy a diamond graded by a tier 1 lab or you accept that you may well be acquiring a lesser quality diamond than what is mentioned on the report if that diamond is graded by a lesser acknowledged lab.

two. Several massive chain stores have large contracts with lesser recognized labs with “softer” diamond grading tips. Some of these softer labs set “suggested replacement values” on the lab studies – values which are greater than what merchants intends sell the diamonds for.

So a salesperson in a chain store might say to you, “Look at the wonderful deal you are getting here. We are selling you this diamond engagement ring for $2500 but the report claims that the proposed substitution value is $4000.” Wow – what a offer – NOT! This is why it is better that you have faith in only unbiased tier 1 labs.

Also bear in head that reputable diamond grading stories are not appraisals and will not offer you appraisal figures. Diamond appraisals are typically grossly inflated and are not one thing you will want to count on.

three. Diamond studies are riddled with disclaimers that specify that absolutely nothing is “certified” or assured and that the labs are not accountable for glitches. In fact, the GIA offers a disclaimer of kinds on their website regarding the use of the word “certify.” The site claims:

“It is incorrect to state that pupils, graduates, their companies, or distinct gemstones are “qualified” by GIA. The Gemological Institute of The us does not certify anybody or everything. Neither a scholar nor a graduate who has been awarded a certificate or diploma, nor a gem which has been graded or identified by GIA has been licensed by GIA”.

So it is possible that you the customer is still left keeping the bag must an inaccuracy in a report is later on uncovered. Courts have frequently ruled that sellers, not labs, are dependable for this kind of errors. Why? Due to the fact the labs indicated beforehand that their reports couldn’t be held liable.

Thankfully, there are a couple approaches to give yourself more purchaser security:

A. You could fly to India where jewelers supply a life time buyback plan to their buyers. Too high-priced to fly?

B. You could locate one particular of the 20% of US jewelers who sell completely bonded diamonds. These are diamonds that are marketed with life time breakage, life span trade-in and lifetime buyback insurance policies.

C. Not as great a treatment as buying a fully bonded diamond but you could purchase a diamond that arrives with an actual “certification” and not a report. “Certified diamonds do arrive with guaranties” albeit for shorter durations.


Some sellers refer to a “diamond report” as a “licensed diamond” but technically this is not proper. From a authorized standpoint, a diamond report is a just an skilled opinion though in actuality, aspects of a diamond grading report are not just thoughts.

For instance, a diamond’s carat (bodyweight) can be accurately decided as well as its cut quality by measuring its optical effectiveness or by referring to a computer product. A certificate on the other hand is a assertion of reality – a doc for which the issuer accepts authorized obligation and will make restitution to the consumer for mistakes.

Some prime diamond grading labs supply each studies and certificates. AGS offers Diamond Quality Paperwork (non-certified reviews) and also Diamond Good quality Certificates. Diamond Top quality Certificates are well prepared exclusively for AGS retail jewelers and delivers guaranties from taking part American Gem Society member retailers.

GCAL certifies it really is diamond grading also. Its 100% income-back again ensure coverage is valid for a time period of two several years from the date on the relevant certification. This policy guarantees the accuracy of the reduce, shade and clarity grades and the carat bodyweight.

A report or certificate ought to will have a amount on it that may or might not be inscribed on a diamond. You will be ready to enter that amount on the internet site of the certifying lab to examine a report’s validity.
