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 in Scottsdale diamonds 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 visual 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 unethical seller may provide a fake one because of the time, trouble and expense he will probably bear which will get a stone graded.
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 not forget the opportunity cost of a jeweler not having the diamond in his store for sale for a few weeks while the grading develops.
However, a diamond grading report may also not be available because the costs which will get one may impact too heavily on the final price of the ring.
For example, a 0. 3ct engagement ring costing $250 say, may cost around $75 to be graded and have the report number inscribed on the girdle on the diamond.
As you search for that ideal diamond engagement ring for your man, you will find that 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 total that the two premier labs are GIA-GTL (Gemological Institute of America’s Treasure Trade Lab) and the AGS (American Treasure Society Laboratories).
The GCAL (Gem Certification and Assurance Lab) even offers well known reports or “diamond certificates” as they are referred to by GCAL.
The GIA has the most effective global reputation for independence and consistency. Because of the 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 private 0 to 10 grading system to evaluate the 4 Cs : a system which is much easier to comprehend than GIA’s grading system. In fact, AGS even goes the excess step by equating their 0-10 rating scale to other designs of rating.
For example, the standard VS1 diamond clarity rating is a 3 on the AGS Diamond Quality Document.
Diamond Revealing : The Drawbacks
- Diamond grading is not standardized or regulated and so you may come across rate 2 labs that employ looser guidelines to the rate 1 grading labs mentioned above.
If you buy a diamond that has been graded by a rate 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 rate 2 lab gets a Gary, L, or lower color rating at a more reputable lab.
A also discounts diamonds graded by lesser known labs by about 15-30% or more. So either you buy a diamond graded by a rate 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 graded by a lesser known lab.
- Many large stringed 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 hopes sell the diamonds for.
So a proctor in a stringed 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. inches Wow : what a deal : NOT! This is why it is advisable that you trust only independent rate 1 labs.
Also keep in mind reputable diamond grading reports are not assessments and don’t offer appraisal figures. Diamond assessments are often grossly overpriced and are not something you’ll want to rely on.
- Diamond reports are riddled with disclaimers that specify that there’s 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. inches The website says:
“It is incorrect to mention that students, graduates, their businesses, or particular rocks are “certified” by GIA. The Gemological Institute of America does not certify anyone or anything. Neither a student nor a graduate who has been worth a certificate or degree, nor a treasure which has been graded or identified by GIA has been certified by GIA”.
It’s the same possible that you the consumer is left holding the bag should an inaccuracy in a report is later discovered. Courts have frequently led that sellers, not labs, are responsible for such errors. Why? Because the labs indicated beforehand that their reports couldn’t be held accountable.
Fortunately, there is a couple ways to give yourself more buyer protection:
A. You could fly to Of india where jewelers give you a lifetime buyback policy to their customers. Very 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 breakage, lifetime trade-in and lifetime buyback policies.
C. Not only good a fix as buying a fully bonded diamond but you could buy a diamond that is included with a true “certificate” and not a report. “Certified diamonds do come with guaranties” albeit for shorter stays.
Some sellers refer to a “diamond report” as a “certified diamond” but technically this is not correct. From a legal viewpoint, a diamond report is a simply an expert opinion though in most cases, areas 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 why the issuer will take culpability 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 have decided exclusively for AGS retail jewelers and offers guaranties from partaking American Treasure 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 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 one specific of the certifying lab to check a report’s validity.
Regions of A Diamond Grading Report
Diamond grading reports are always increasing 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 & Side Style: This is the outline and the cutting style used for the side arrangement. There are 3 basic side styles : “brilliant cut, step cut and mixed cutting style” and 12 basic shapes such as 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 statistic 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’ve got to do is weight the stone.
Color Grade: This informs you the degree of color absence in the diamond. The less color the higher the grade.
Diamonds are typically graded from D-Z; the closer to “D” the whiter the diamond. You must never 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 assessments for pebbles that are mounted.
Clarity Grade: Virtually every diamond has internal defects called inclusions and external defects called scars. A diamond is graded according to the size, type, location and amount of these flaws.
Clarity grades range from Immaculate (FL) : Included. Labs use a couple experts to grade the clarity of a diamond in order to create a more accurate reading.
Cut Grade: More recent diamond reports your internet site 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 have the improve, symmetry, fluorescence and proportion. Provided with this information, you are better able to make an assessment of products you can diamond that is mounted in an engagement ring.
