About Us


Memory DiamondFounded in 2006, Gemory LLC uses nanotechnology to perform a unique and innovative process of injecting nano-photographs into diamonds and other gemstones. This process can be performed on Gemory's own natural diamond called The Memory Diamond or on the consumer’s diamond.

This process called DiamondPure is performed utilizing the finest, most precise nanotechnology, atom-by-atom, and cannot be found anywhere else. What makes our process unique is that our injections are in grayscale, placed beneath the intact surface of the stone and are of a much finer quality than any other diamond marking service. As a result we have the ability to create a high resolution photograph inside your diamond.

Other diamond marking companies have been using an intrusive technology for the last 25 years that melts away the surface of the stone and leaves a black residue that can easily be damaged by normal cleansing. The old method only allows for letters, numbers and crude black logos to be inscribed on the stones.

Using nanotechnology, our superior process allows for perfect grayscale images to be injected inside diamonds and other gemstones. All of our injections are permanent and cannot be scrubbed off because they are actually done below the diamond’s surface, allowing the nano-photographs to be protected from harm.

Our inscriptions are nanoscopic and invisible to the naked eye. They can be viewed with GemmaView, Gemory's proprietary hand held portable viewing device. These devices are only available on our website or our dealers.

At Gemory, our mission is to deliver our innovative high resolution nano-photograph diamond injection services to the entire world without wavering in our commitment to customer satisfaction and superior quality workmanship.
