A parti-colour orange, pink and red synthetic Sapphire boule made to simulate the rare and highly sought-after Padparadscha Sapphire colour.

The flame fusion, or Verneuil method is a simple and cost-effective way of creating synthetic Corundum, resulting in  bottle-shaped forms known as "Boules".

They are usually split down their length before faceting, as is the case of this example.

The process results in relatively large, optically pure specimens originally intended for use in the production of early laser technology but have subsequently used extensively as a cheap alternative for natural Sapphire and Ruby in jewellery.

These boules are usually cut into gems and are not commonly found in their original state.
