Citrine

Citrine

Citrine is the clear yellow or golden form of the mineral quartz. As such it is related to amethyst which is the purple form of quartz, and also to rock crystal which is the colourless variety.

Dual Personality

It is possible for some specimens of quartz to be different colours in different areas. Amethyst and citrine are varieties of quart which can both occur in the same stone. As our photograph clearly shows, the difference in colour at the two ends create a striking contrast. Such stones are sometimes called ametrines, but we think they could equally well be called citrysts or citrethysts.

Hardness

The hardness of citrine is 7, and appears on the Moh scale as quartz.
