Centre-Fused Colour Treatment

This process has two steps. First, a layer of diffusion treatment colour is applied to a piece of colourless rough. Next, a second piece is fused to the coloured piece using a high pressure and high temperature (HPHT) process. This leaves the colour layer on what will become the stone’s girdle plane.

The end result is a single stone with extraordinary colour. Unlike a surface treated gem, the colour won’t scratch off, and neither chemicals nor the heat of a torch will affect it.
