The Museum of Faceting Technology project began in February of 2018. At first it was devised as a personal collection but the scope quickly changed as more machines were acquired and donated. As the collection grew, it began to become a tangible representation of the worldwide culture of gemcutting.

In five years, the museum has acquired 106 machines, faceting heads, and handpieces from 24 different countries. The end goal will be to have at least one style of machine from each country that has a history of faceting. In some cases, such as the United States and Australia, there are dozens of types of faceting machines going back at least 100 years. In these cases, care will be taken in selecting machines for their uniqueness and antiquity.

We hope to put the museum collection of public display soon but for the time being you can experience the collection through the museum catalog. You can click to download a copy of the catalog here:
