Categories :

Not all sellers give diamond grading lab reviews (aka diamond quality stories) to their customers. So my common guidance to you is to preserve your cash in your pocket when dealing with these kinds of jewelers 訂婚鑽戒.

Only purchase a diamond engagement ring if it will come with the unique diamond good 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 different qualities and eventually assists you make a far more knowledgeable acquiring selection.

A retailer may possibly minimize corners and not supply a lab report or an unscrupulous vendor could supply a fake a single simply because of the time, trouble and price he’ll bear to obtaining a stone graded .

Yeah – there is a cost for grading a diamond (even though that value is sooner or later paid by the buyer), furthermore the shipping and delivery and insurance policies costs for sending the diamond to the lab. And enable us not overlook the possibility expense of a jeweler not having the diamond in his store for sale for a handful of months although the grading takes spot.

Nevertheless, a diamond grading report may possibly also not be available due to the fact the costs to obtaining 1 might effect also intensely on the ultimate price of the ring.

For example, a .3ct diamond ring costing $250 say, could expense close to $75 to be graded and have the report amount inscribed on the girdle on the diamond.

As you look for for that best diamond engagement ring for your sweetheart, you are going to find that there is an alphabet soup of labs declaring to supply reputable diamond grading stories. But I would only set my income on…

The Premier Diamond Grading Lab Reviews

Yes, all diamond top quality reviews are not designed equal. Inside 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 Society Laboratories).

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

The GIA has the strongest world-wide status for independence and consistency. Due to their constant colour and clarity strictness guidelines, the globe’s greatest and most pricey diamonds have been despatched there for grading many years. In 2006, GIA-GTL additional a two-dimensional minimize grading system for round amazing diamonds.

AGS utilizes the strictest minimize specifications in the market. It uses a a few-dimensional mild overall performance metric that can grade numerous diamond styles. In reality, it is the only lower grading system that is recognized by the scientific neighborhood.

What is a lot more, its Diamond Quality Doc makes use of a distinctive and proprietary to ten grading system to assess the four Cs – a program which is less difficult to understand than GIA’s grading system. In truth, AGS even goes the additional phase by equating their -ten score scale to other kinds of ranking.

For illustration, the typical VS1 diamond clarity score is a three on the AGS Diamond Quality Document.

Diamond Reporting – The Downsides

1. Diamond grading is not standardized or controlled and hence you may arrive across tier 2 labs that utilize looser guidelines to the tier 1 grading labs pointed out earlier mentioned.

If you get a diamond that has been graded by a tier 2 lab, you may possibly conclude up paying out much more for a lesser top quality diamond. So for example, a diamond rated a “F” in colour at a tier two lab might get a G, H, or decrease shade score at a far more reliable lab.

The business also reductions diamonds graded by lesser identified labs by about fifteen-30% or much more. So both you only acquire a diamond graded by a tier 1 lab or you take that you may be acquiring a lesser top 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 enormous contracts with lesser known labs with “softer” diamond grading recommendations. Some of these softer labs place “advised replacement values” on the lab studies – values which are larger than what shops intends market the diamonds for.

So a salesperson in a chain shop could say to you, “Appear at the great deal you are acquiring below. We are offering you this diamond engagement ring for $2500 but the report claims that the proposed alternative worth is $4000.” Wow – what a offer – NOT! This is why it is much better that you have faith in only unbiased tier one labs.

Also bear in thoughts that trustworthy diamond grading reviews are not appraisals and do not offer appraisal figures. Diamond appraisals are usually grossly inflated and are not anything you are going to want to depend on.

three. Diamond reviews are riddled with disclaimers that specify that nothing is “licensed” or guaranteed and that the labs are not accountable for mistakes. In truth, the GIA offers a disclaimer of types on their web site regarding the use of the word “certify.” The site states:

“It is incorrect to point out that pupils, graduates, their businesses, or certain gemstones are “certified” by GIA. The Gemological Institute of The usa does not certify anybody or everything. Neither a scholar nor a graduate who has been awarded a certification or diploma, nor a gem which has been graded or discovered by GIA has been licensed by GIA”.

So it is feasible that you the client is left keeping the bag should an inaccuracy in a report is later on found. Courts have usually dominated that sellers, not labs, are accountable for this kind of glitches. Why? Since the labs indicated beforehand that their stories couldn’t be held liable.

Fortunately, there are a pair techniques to give oneself more purchaser security:

A. You could fly to India exactly where jewelers supply a life time buyback coverage to their consumers. Way too high-priced to fly?

B. You could discover 1 of the twenty% of US jewelers who sell totally bonded diamonds. These are diamonds that are sold with lifetime breakage, life span trade-in and lifetime buyback insurance policies.

C. Not as good a treatment as acquiring a completely bonded diamond but you could get a diamond that will come with an true “certification” and not a report. “Accredited diamonds do appear with guaranties” albeit for shorter durations.


Some sellers refer to a “diamond report” as a “accredited diamond” but technically this is not appropriate. From a lawful standpoint, a diamond report is a simply an professional opinion even though in actuality, elements of a diamond grading report are not just opinions.

For instance, a diamond’s carat (bodyweight) can be correctly established as effectively as its reduce quality by measuring its optical effectiveness or by referring to a personal computer product. A certification on the other hand is a statement of truth – a doc for which the issuer accepts legal responsibility and will make restitution to the client for mistakes.

Some leading diamond grading labs supply the two reports and certificates. AGS delivers Diamond High quality Documents (non-qualified studies) and also Diamond High quality Certificates. Diamond Top quality Certificates are ready exclusively for AGS retail jewelers and provides guaranties from participating American Gem Culture member merchants.

GCAL certifies it’s diamond grading also. Its 100% money-again ensure coverage is valid for a time period of two many years from the day on the relevant certificate. This coverage makes certain the accuracy of the reduce, colour and clarity grades and the carat excess weight.

A report or certificate should will have a variety on it that could or may possibly not be inscribed on a diamond. You will be in a position to enter that number on the internet site of the certifying lab to check a report’s validity.

The Report #. This quantity is presented and recorded in a lab’s document and may or could not be inscribed on a diamond’s girdle.
