Apatite comes in many colours (white, yellow, brown, red, pink, purple, blue, green) depending on the mineral predominance. 3 minerals are present - Fluorapatite, Chlorapatite and Hydroxylapatite.
Named from the Greek word apate, which means "deceit", Apatite has a similar appearance to many other minerals for example beryl, tourmaline, olivine, quartz and peridot.
Apatite has a translucent to transparent texture and its surface quality is vitreous or glass-like.
It is found in Mexico, Norway, Russia and the USA.
The cabochons (uncut stones) used for jewellery are rarely available in large sizes and the most popular colour is a rich lagoon blue/green.
Allegedly, the blue/green colour facilitates spiritual guidance, enhances public speaking and group communication.
