Kyanite, a aluminium silicate mineral often found in groups of light-blue crystals. This beautiful specimen was mined in Minas Gerais, Brazil. A similar variety is also found in Harts Ranges, NT, Australia.
Citrine is probably one of the most talked about minerals going around. Is it natural, is it heat treated and does it matter!?

Amethyst comes in a variety of different shades of purple depending on the locality, usually caused by impurities of iron or manganese compounds. This piece is particularly special due to its formation known as elestial amethyst.
