Antique unheat treated Ceylonese sapphire and diamond ring

Centuries ago, people discovered that if you put a sapphire or ruby into a fire it will improve its colour and clarity, and people have been heat treating sapphires and rubies ever since for this reason. This treatment is worldwide accepted as a normal treatment and not deceiving in any way and is accepted as a standard treatment for sapphires and rubies as it remains stable and does not damage the stone. However set into this ring is a truly magnificent unheat treated Ceylonese sapphire that displays the most beautiful colour and clarity.

This gorgeous sapphire measures 2 carats in weight and the colour is so beautiful to admire and shows why Ceylonese sapphires are regarded as the finest in the world. With such a beautiful cornflower blue colour to it, the sapphire also has a wonderful clarity that allows you to see right through the stone, and allows so much light to bounce and dance through the sapphire.

Set into a hand made 18 carat yellow gold setting, the sapphire is highlighted by ten European cut diamonds as well as a further two on each side. These diamonds total an impressive 1.46 carats and sparkle magnificently.

With the top cluster section measuring 14.3mm in diameter, this ring certainly makes such an impact on the finger.

A brief history on heat treating sapphires and rubies:

Sapphires and rubies have been heat treated for centuries to improve their colour and clarity and this is a worldwide accepted practice. It should be clarified that a sapphire or ruby that has undergone some form of heat treatment is still a natural gemstone from the ground and is not a synthetic/man made stone and the treatment is completely stable. Lately on the market there is a technique of glass filling or lead filling stones which will improve the colour of a natural gemstone, however this treatment is very unstable and the stone may look worse in a few years.
