FAQs

Why does every diamond have a unique
GEMPRINT® pattern?

The typical round brilliant diamond has 57 facets. The arrangement and relation of each of these facets to one another is always slightly different; each facet can be a slightly different shape, size, and angle. There are an infinite number of possible combinations and an infinite number of ways a diamond reflects a beam of light. This is why every diamond, even those of the same shape and weight, has a unique GEMPRINT® pattern.

Does the GEMPRINT® pattern printed relate to the diamond's inclusions or clarity?
No. The GEMPRINT® is a distinct optical reflection pattern of a laser beam of light. Inclusions can play a part in the uniqueness of the GEMPRINT® pattern if they alter the path of the beam of light, but the pattern does NOT represent the location of inclusions.

Does the GEMPRINT® identification ever wear off?
GEMPRINT® is a permanent identification technology for loose and mounted diamonds that does not physically mark the diamond. However, GEMPRINT® does become invalid if the diamond is significantly re-cut, in which case the diamond should be sent back for a new GEMPRINT® registration.

How Accurate is GEMPRINT®?
GEMPRINT® has undergone rigorous testing on tens of thousands of diamonds around the globe - many of which appear identical to expert gemologists.   Each time GEMPRINT® has been able to uniquely identify a cut and polished diamond without the aid of any external markings.  GEMPRINT® has been called the fingerprint system for diamonds.

How long does it take to GEMPRINT® a diamond?
The Gemprinting process takes less than 30 seconds per diamonds.

Does a diamond have to be loose to be Gemprinted?
No, GEMPRINT® works equally well on loose or mounted diamonds.

Are there are other methods of identifying diamonds?
The most common invasive methods are various forms of laser inscription, which inscribe numbers or letters on the girdle of the stone.  Unfortunately, laser inscriptions can be easily removed or altered either intentionally, or during the setting process of loose diamonds into diamond jewelry.  While still the most common form of identification, it is not necessarily a permanent identifying mark like GEMPRINT®.
