Not all sellers provide diamond grading lab reports (aka diamond quality reports) to their consumers. So my general advice to you is to keep your money Scottsdale diamonds in your pocket when dealing with such jewelers.
Only purchase a diamond engagement ring if it comes with the original diamond quality report.
A lab report is an independent evaluation of the 4Cs of a loose diamond and includes a plotted diagram of the stone’s clarity characteristics and a video representation of the stone’s proportions. Having such a report allows you to compare diamonds of different qualities and ultimately helps you make a more informed buying decision.
A retailer may cut corners and not provide a lab report or an dishonest seller may provide a fake one because of the time, trouble and expense he will bear that will get a stone ranked.
Yeah — there is a price for grading a diamond (though that cost is eventually paid by the consumer), plus the shipping and insurance charges for sending the diamond to the lab. And let us keep in mind the opportunity cost of a jeweler not having the diamond in his store for sale for a few weeks while the grading occurs.
However, a diamond grading report may also not be around because the costs that will get it’s possible to impact too heavily on the final price of the ring.
For example, a 0. 3ct band costing $250 say, may cost around $75 to be ranked and have the report number inscribed on the girdle on the diamond.
As you search for that ideal diamond engagement ring for your love, forex trading there is an alphabet soup of labs claiming to provide reputable diamond grading reports. But I would only put my money on…
The Premier Diamond Grading Lab Reports
Yes, all diamond quality reports are not created equal. Within the industry, it is a opinion that the two premier labs are GIA-GTL (Gemological Institute of America’s Diamond Trade Lab) and the AGS (American Diamond Society Laboratories).
The GCAL (Gem Certification and Assurance Lab) now offers respectable reports or “diamond certificates” as they are referred to by GCAL.
The GIA has the most robust global reputation for independence and consistency. Because of their constant color and clarity strictness guidelines, the globe’s largest and most expensive diamonds have been sent there for grading decades. In 2006, GIA-GTL added a two-dimensional cut grading system for round brilliant diamonds.
AGS uses the strictest cut standards in the industry. It uses a three-dimensional light performance 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 more, its Diamond Quality Document uses a unique and exclusive 0 to 10 grading system to gauge the 4 Cs — a system which is safer to comprehend than GIA’s grading system. In fact, AGS even goes the additional step by equating their 0-10 rating scale to other styles of rating.
For example, the traditional VS1 diamond clarity rating is a 3 on the AGS Diamond Quality Document.
Diamond Canceling — The Drawbacks
- Diamond grading is not standard or regulated so because of this you may come across collection 2 labs that employ looser guidelines to the collection 1 grading labs mentioned above.
If you buy a diamond that has been ranked by a collection 2 lab, you may end up paying more for a lesser quality diamond. So for example, a diamond rated a “F” in color at a collection 2 lab could get a Grams, They would, or lower color rating at a more reputable lab.
The also discounts diamonds ranked by lesser known labs by about 15-30% or more. So either you merely buy a diamond ranked by a collection 1 lab or you accept that you might be buying a lesser quality diamond than what is stated on the report if that diamond is ranked by a lesser known lab.
- Many large archipelago stores have huge contracts with lesser known labs with “softer” diamond grading guidelines. Some of these softer labs put “suggested replacement values” on the lab reports — values which are higher than what stores expects sell the diamonds for.
So a merchant in a archipelago store may say to you, “Look at the great deal you are getting here. We are selling you this diamond engagement ring for $2500 but the report says that the suggested replacement value is $4000. inch Wow — what a deal — NOT! This is why it is best that you trust only independent collection 1 labs.
Also be aware that reputable diamond grading reports are not evaluations , nor offer assessment figures. Diamond evaluations are often grossly filled with air and are not something you’ll want to rely on.
- Diamond reports are riddled with disclaimers that specify that there is nothing “certified” or guaranteed and that the labs are not accountable for errors. In fact, the GIA offers a disclaimer of sorts on their website regarding the use of the word “certify. inch The website says:
“It is incorrect to convey that students, graduates, their businesses, or particular crystals are “certified” by GIA. The Gemological Institute of America does not certify anyone or anything. Neither a student nor a graduate who has been honored a certificate or diploma or degree, nor a diamond which has been ranked or identified by GIA has been certified by GIA”.
Therefore it is possible that you the consumer is left holding the bag should an inaccuracy in a report is later discovered. Courts have frequently decided that sellers, not labs, are responsible for such errors. Why? Because the labs indicated beforehand that their reports couldn’t be held responsible.
Fortunately, a large couple ways to give yourself more buyer protection:
A. You could fly to The indian subcontinent where jewelers provide a lifetime buyback policy to their customers. Too costly to fly?
B. You could find one of the 20% of us jewelers who sell fully bonded diamonds. These are diamonds that are sold with lifetime break, lifetime trade-in and lifetime buyback policies.
C. Significantly less good an answer as buying a fully bonded diamond but you could buy a diamond that accompany an authentic “certificate” and not a written report. “Certified diamonds do come with guaranties” albeit for shorter trips.
Some sellers refer to a “diamond report” as a “certified diamond” but technically this is not correct. From a legal understanding, a diamond report is a simply an expert opinion though literally, facets of a diamond grading report are not just opinions.
For example, a diamond’s carat (weight) can be accurately determined as well as its cut grade by measuring its optical efficiency or by referring to a computer model. A certificate on the other hand is a statement of fact — a document which is the issuer takes responsibility and will make restitution to the consumer for mistakes.
Some top diamond grading labs offer both reports and certificates. AGS offers Diamond Quality Documents (non-certified reports) and also Diamond Quality Certificates. Diamond Quality Certificates are ready exclusively for AGS retail jewelers and will be offering guaranties from engaging American Diamond Society member stores.
GCAL certifies it’s diamond grading also. Its 100% money-back guarantee policy is valid for a period of two years from the date on the applicable certificate. This policy ensures the accuracy of the cut, color and clarity grades and the carat weight.
A written report or certificate should will have a number on it that may or may not be inscribed on a diamond. You will be able to enter that number over the internet of the certifying lab to check a report’s validity.
Components of A Diamond Grading Report
Diamond grading reports are always growing but certain element should remain the same. For instance, the:
The Report #. This number is given and recorded in a lab’s record and may or may not be inscribed on a diamond’s girdle. You can enter the report number on a grading lab’s website to check the authenticity of the diamond quality report or to get more information about the diamond.
Shape & Part Style: This is the outline and the cutting style used for the part arrangement. There are 3 basic part styles — “brilliant cut, step cut and mixed cutting style” and 12 basic shapes together with notables such as round brilliant and princess cut” diamonds.
Measurements: This refers to size (not weight) of a diamond. Size includes dimensions such as length, width, weight and diameter. A rating is typically listed to the hundredth of a millimeter. Measurements play a huge role in how a diamond sparkles.
Carat Weight: The weight of a diamond is measured to the hundredth of a carat and some even provide such measure to the thousandth of a carat (1. 123ct. ). Carat is the most objective and the easiest to understand of the 4Cs because all you have to do is weight the stone.
Color Grade: This lets you know the quality of color absence in the diamond. The less color the higher the grade.
Diamonds are typically ranked from D-Z; the closer to “D” the white the diamond. Don’t ever see diamond color range such as (G-H, I-J-K, and so on) on a diamond report. You should only see color ranges on evaluations for rocks that are mounted.
Clarity Grade: Virtually every diamond has internal skin problems called inclusions and external skin problems called spots. A diamond is ranked according to the size, type, location and amount of these flaws.
Clarity grades range from Exquisite (FL) — Included. Labs use a couple experts to grade the clarity of a diamond in order to think of a more accurate reading.
Cut Grade: More recent diamond reports will include a cut grade for standard round brilliant diamonds. Cut takes into consideration the brilliance, fire and scintillation of the diamond. Cut grade ranges from Excellent — Poor.
Other elements you may come across on a diamond report add the gloss, proportion, fluorescence and proportion. Television with this information, you are better able to make an assessment of the standard of diamond that is mounted in an engagement ring.
