Scoring 8.5 on the Mohs scale of hardness and with solid toughness, cubic zirconia is highly durable and suitable for use on all types of jewellery.
While most cubic zirconia has been cut and polished only, the ‘fancy’ varieties have been treated with Thermal Colour Fusion (TCFTM), an innovative and environmentally friendly chemical heat treatment patented by Swarovski, which leaves lasting results.
Cubic zirconia's perfect crystal structures have made the beauty and popularity of the innovative stone irrefutable. In the 1970s, it became an affordable alternative to diamonds. The origins of naturally mined diamonds can be difficult to determine, but cubic zirconia is fully traceable.
