Each entity grades and describes gemstones differently and sometimes the difference is significant. Several laboratories exist and it’s really important to learn which are dependable and reliable, and those are not.
Because precious stone certificates aren’t created equal, the purchase price and value of diamond jewelry are not similar across different qualifications. Make sure that you purchase diamonds with a qualification from an extremely reputable grading entity and that you review the precious stone thoroughly before purchase.
What To Watch Out For In A Diamond Certification
With regards to comparing laboratory grading entities, it’s more important to look for regularity rather than strictness of grading.
For instance, the GIA won’t grade a precious stone the same manner the IGI rates a gem. The stability of the color and Clearness grades and occasionally the Trim grades is only as effective as the certifying lab’s reputation. But if one laboratory regularly provides single Clarity class greater than another laboratory, that laboratory is in no way less “authentic.”
To highlight the value of this concern, take Color levels for example. We recommend keeping an H color or better when placing a precious stone in an environment such as this one. It may seem you have found the ideal gemstone with an H color diamond with an IGI license. But when you have it home, you understand the precious stone has a yellowish tint. It is because the gemstone is very much like an I color by GIA certification and the IGI just offers a relatively weak certificate.
Instead of simply comparing marks between accreditations, look for persistence within the entity’s grading decisions.
Different documentation labs give different results. Every laboratory has its quirks. Some are looser in grading Color, while some are inconsistent with Quality. Some labs will usually update specific Colors and variations, while others prefer particular agreements of inclusions.
Smart diamonds companies utilize this knowledge, gained from mailing thousands of gemstones to different labs each month to increase their results. Knowing which labs are dependable and constant can help you avoid investing in a gemstone worth significantly less than what the license is saying to be true.
Gemstone grading is subjective
All precious stone grading is subjective and unlike popular belief there is not really a central company that mathematically identifies just what a “G” Color is or what an “SI1” Quality looks like. If one laboratory regularly says that one color quality is a “G” while another laboratory will regularly be calling that same color “H”, it’s correctly suitable and reasonable as long as they do so consistently.
It is important to note that even though an entity is regular in its grading, it generally does not indicate the entity is trustworthy and reliable. Buying a precious stone with an unreliable certificate at an unrealistic price is not right even if the entity constantly grades diamond jewelry this way because you aren’t getting the worthiness for the purchase price you’re paying.
GIA Certified Loose Diamonds
The GIA (Gemological Institute of America) is the most well respected and renowned precious stone grading entity. They are really incredibly constant and give the greatest satisfaction when purchasing any diamonds. GIA does not have any financial stake in the sales of the diamonds and evaluates gemstones on a number of attributes and elements, including:
Cut level (Excellent, Very Good, Good, While)
Color level (which range from D to J)
Clarity quality (IF, VVS1, VVS2, VS1, VS2, SI1, SI2)
Measurements (in millimeters)
Slicing style and precious stone shape
Diamond plot demonstrating all blemishes and inclusions
Laser beam inscription (if appropriate)
All in all, GIA certified loose diamonds have a reputation for great Color and Clearness, the most subjective scales, and most rigorous evaluation. Due to GIA’s high reputation, proven reliability and background, we recommend only buying GIA certified loose diamonds.
Why buy GIA Certified Loose Diamonds?
Each precious stone is licensed and priced in line with the four “C’s” (karat, color, quality, and trim). But perhaps you have never pondered who levels the precious stone a sales rep shows you? Quite simply, how will you know that a diamond said to be a G color and VS1 clearness is really a G color, VS1 quality diamond?
Let`s say that you get a precious stone graded as 0.76 karats, G color and VS1 quality. To make sure that our grading of the diamonds is current, you choose to take it to ten different precious stone graders. You will likely discover that the ten appraisers offer you at least six different evaluations, which might differ from the statement at of others. Does this imply that they were wrong, and sold the diamonds to you in an unethical or deceptive manner? Maybe five our evaluation was valid and the other jewelers were providing you with incorrect information. How will you compare precious stone prices objectively if one precious stone can receive so many gradings?
Now you almost certainly understand what an average shopper must go through in search of that special stone. Isn’t there an improved and simpler way to do this? YES, IT EXISTS! Look for a gemstone that is certified, not by simply anyone, but by the GIA (Gemological Institute of America). All diamonds experts and jewelers know what a “GIA certificate” is. The GIA’s grading is undeniably regarded throughout the diamond industry as the utmost accurate and impartial judgment as it pertains to grading gemstones.
