About Opals
This beautiful gemstone displays almost magical qualities of transparent and opalescent colors that range from milky whites and creamy yellows through to medium hues of blues and greens and darker tones with reds, browns, greys and even black. The Fire Opal is a stunning red-orange color and the Black Opal is one of the rarest and most sought after gemstones.

Tourmaline Colors:

About Tourmaline
Scientifically, Tourmaline is not a single mineral, but a complex silicate of boron and aluminium that contains varying amounts of iron, magnesium, manganese, calcium, sodium and potassium. It is a gemstone that is quite distinct from other gem species. According to Ruskin’s “Ethics of the Dust”, the chemistry of Tourmaline is “more like a medieval doctor’s prescription than the making of a respectable mineral”.
