GCAL’s Gemprint® is one of the smartest safeguards that you can obtain for your diamond. Gemprint® is a non-invasive, positive identification technology that records the unique optical ‘fingerprint’ of each diamond. Just like a human fingerprint, every diamond has a unique Gemprint®.
THREE WAYS YOU BENEFIT FROM GEMPRINT® REGISTRATION:
1. Investment Protection The Gemprint® registration of your diamond is a court-accepted means of irrefutable evidence proving ownership and protecting your investment. If your diamond is ever lost or stolen, notify Gem Certification & Assurance Lab immediately. Your diamond will be flagged in the Gemprint® database helping to speed recovery.
2. Peace of Mind Even if your diamond has been removed from its setting, a Gemprint® allows you to positively identify it. You’ll never have to worry about tampering or fraudulent stone switching when leaving your diamond to be reset, repaired or cleaned. Gemprint® allows you to verify ownership with absolute confidence.
3. Insurance Discounts Gemprint® is recognized by most insurance companies as a safeguard for diamonds. Many insurance companies offer a 10% discount if your diamond is registered in GCAL’s international Gemprint® registry at DiamondID.com. Some insurance companies even require a Gemprint for insurance replacement and for high-risk value diamond jewelry.

CRYSTAL BEAM MELODY

With over 40 years in the diamond industry, Sir Gabriel (Gabi) Tolkowsky is recognized as the world’s most foremost master cutter and diamond expert. Never content to rest on industry standards, he is an innovator who continues to create some of the most compelling diamond innovations. One of his most unexpected projects is Crystal Beam Melody, an invention that uses the unique optical response of a gemstone to produce a song. This optical response is found using Gemprint®, the world’s most sophisticated, non-invasive diamond identification and registration system, owned by GCAL.

How does it work? Simply put, a diamond’s unique sparkle pattern (found using Gemprint®) is converted to a sound transfer file based on algorithms. As the optical response of each gemstone is unique, the musical representation will be unique.

With Crystal Beam Melody, you can not only see and touch diamonds, but you can listen to their particular and unique melodies. The current fragile state of the world will probably make people aware that one of life’s great pleasures is enjoying joyful sensory experiences, especially ones that arose from natural discoveries.

You can sample Crystal Beam Melody music when viewing the splash page on this site and contact GCAL to purchase your diamond’s unique Crystal Beam Melody for a cost of $75 per diamond.
