Abstract:

A method of enabling marking of gemstones, comprising the steps of: manufacturing, at a manufacturing site, stencils with cutouts arranged in marking patterns; sending the stencils from the manufacturing site to marking sites at which marking of the gemstones is to be performed; adhering the stencils on, and in direct contact with, the gemstones to be marked at the marking sites; filling the cutouts with a fusible material; and inscribing the gemstones with the marking patterns of the stencils adhered to the gemstones at each marking site by heating the fusible material at each marking site to a temperature sufficient to melt the fusible material and form cavities in the gemstones, the cavities in the gemstones constituting the marking patterns.
