Pleochroism is rare in gemstones and it is this quality that makes the blue colour of tanzanite (due to the presence of vanadium) so extraordinary. Tanzanite is trichroic- showing blue, purple and yellow in different directions of light- making the blue colour richer and deeper in the naked eye. But this blue colour that Cassandra so loves to design with, comes at a price because the stones are fragile and should be worn with great care. The birthstone for December- it is a reminder of those wintery moonlit nights.
All Cassandra Goad jewellery is designed and made in the
workshops in London.
As a gemmologist, the chemical composition and properties of gemstones have always fascinated Cassandra. Ever in search of the unusual and rare, she travels the world to source beautiful gemstones, either in the rough or cut form. The craftsman works as an artist recreating the design in metal, his interpretation is vital to the overall feel of the jewel. The jewel is then mounted, assayed , polished and set. Many of Cassandra's jewels can be hand engraved with a personal message to make a unique bespoke gift.
