How important is fluorescence?

Since fluorescence influences the apprearance and especially the price of the stone it is an essential parameter to consider. When exposed to UV light a fluorescent diamond emits blue light.

Why do I need a certificate?

Certificates are indispensable today: With further standardization in diamond grading and rising quality standards in the jewelry industry independent third-party quality assurance by gemological institutes have become a necessity. We recommend certification by GIA, HRD or IGI that have the highest grading standards and procedures. For example: Diamonds are examined anonymously and the grader will never know who the stone belongs to. Certificates also help customers in making an informed buying decision, serve as verification for insurances and last but not least allow for doubtless identification of a diamond at any time. There are no two identical diamonds. Also, most stones come with a laser inscription of the certificate number on the girdle.
