What is Gemprint?

Gemprint^TM is a proprietary patented technology provided by Gemprint Corporation to the world’s diamond industry.   Gemprinting is a non-invasive method of identifying diamonds using a laser-based scanning device that interfaces with a PC.  Each cut diamond has a unique pattern that can be identified, even those that appear to expert gemologists to be similar.   The recorded pattern is then sent via modem to Gemprint’s central database which keeps a secure international registry of diamonds.  A Gemprint certificate is issued to establish the identity and ownership of the diamond.  See How It Works for a further explanation.

Who uses Gemprint?

• the registration of diamonds and jewelry provides assurance that the purchased diamond can be identified in case of loss, theft or stone-switching.

How accurate is Gemprint?

Gemprint has undergone rigorous testing on thousands of diamonds - many of which appear identical to expert gemologists.   Each time Gemprint has been able to uniquely identify a cut and polished stone without any external markings.  Gemprint has been called the "DNA of diamonds."

How long does it take to Gemprint a diamond?

The Gemprinting process takes less than 30 seconds for an individual diamond.  To compare an individual diamond against the entire database would take a few minutes.

Do I have to remove the diamond from my ring or setting in order for it to be Gemprinted

No.  The Gemprint Isi scanner allows mounted stones to be Gemprinted.

How do I get my diamond Gemprinted?

We use Gemprint Technology as part of our inventory control.  All diamonds entering and leaving our brokerage are run through the Gemprint machine for security purposes.  If you would like to register a diamond purchased from our company, simply request the certificate from us.  The cost to register is only $45.00 and well worth the peace of mind.  In addition, many insurance companies offer a discount off of the premium for diamonds registered with Gemprint. 

Are there other methods of uniquely identifying diamonds?

The most common invasive methods are various forms of laser inscription, which inscribe numbers or letters on the girdle of the stone.  The disadvantage to laser inscription is that there is not an international registry that enables the diamond to be returned to the rightful owner.  Furthermore, inscriptions can be forged and polished off of the diamond by thieves.
