Here is a very unusual parti-colour sapphire from Tanzania. It is an interesting gemstone showing a purple, blue, grey combination of colours. The sapphire is fascinating to look at, the parti colours really to blend together nicely. The gem is an excellent size and would be perfect for an amazing ring setting. The design is an Asscher-like square step cut and this suits parti-colour sapphires perfectly allowing the various hues to be seen within the stone. A very fine sapphire.
