lapidary technique “Photon Phacets”™

Once again, Michael garnered 1st Prize in the American Gem Trade Association's Spectrum Awards “Cutting Edge” Competition 2009 - Combination Cuts.

The winning entry is an 89.79 ct. Brazilian Aquamarine that utilizes Michael’s new lapidary technique “Photon Phacets” ™

The piece was inspired by the phenomenon of melting ice to water. It is titled “Metamorphosis”.

Dyber is well known for optical effects and makes the diamond tooling necessary for his designs in his New Hampshire studio. Now, with Photon Phacets, he's created facets within the gemstone. “It has been a journey to produce facets that are optically correct,” he says. “The Photon Phacets™ reflects not only light, but image. What is reflected can be changed at will during its materialization.”
