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.
Misnomers
Citrine is often incorrectly and ignorantly sold as topaz. Although topaz and citrine can often be similar colours, they are both completely distinct gemstones. Often the owners and wearers of citrines ring call them topaz, presumably along the lines of wishful thinking. Many topaz are a richer colour than citrine,containing more orange colouration.
