Learn about different diamond grading companies and their certification processes. Read our full guide to understand diamond certificates and their importance.
Diamond certificate generation is the process of grading and testing a diamond by an independent gemology lab. The certified gem lab assesses the diamond for its 4C attributes that include color, clarity, carat, and cut. The diamond is labeled and sent back to the diamond manufacturers and further to the certified diamond dealers.
To ensure that the diamond you purchase is of high quality, you should always buy diamonds that have certificate assurance. Diamonds that are certified will always be verified by a third party, experienced gemologists.
Benefits of a Diamond Certificate
A diamond verified by a certified diamond dealer has been sealed for its quality. You purchase a diamond based on its true attributes and features rather than the bogus sales pitch of the seller.
1). Certified diamonds pose a higher value compared to non-certified diamonds. The resale price is also higher.
2). Not every diamond appraiser has the equipment to detect whether the diamond is natural or lab-created. Only authentic diamond testing agencies have access to such machines. Therefore, a diamond certificate proves that the diamond tested is definitely a natural diamond.
3). Diamond certificates pose an unbiased value on the quality. Diamond certification can differ from jeweller to jeweller but certification from approved gem labs are authentic and give the same results throughout.
4). It becomes easier to compare a diamond according to its certified 4Cs rather than relying on the visual representation.
