ALEXANDRITE COLOUR-SOME WITH COLOUR CHANGE OR COLOUR SHIFT

NATURAL TOPAZ- FACETED

TREATMENT-CENTRE FUSED ASSEMBLED

NICE COLOUR


Center-Fused Color Treatment

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

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