Along with each diamond you’re considering, you should obtain and review its laboratory certification. This laboratory report or qualification will be granted by a grading entity and represents various components of the gemstone, such as Color, Quality, length. Trained professionals examine, scrutinize and gauge the diamond jewelry using professional tools, like a loupe or microscope.
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 accreditation, 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:
- Girdle thickness
- 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
- Carat weight
- Table %
- Depth %
- Culet size
- Proportion diagram
- Polish grade
- Diamond plot demonstrating all blemishes and inclusions
- Fluorescence grade
- Laser beam inscription (if appropriate)
- Security features
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?
