Comments : The name citrine is derived from its lemon-yellow colour. It is a beautiful stone and actually quite a rare member of the quartz family. You wouldn't think so from the amount of citrine that is available in the marketplace. Alot of the commercial citrine is actually amethyst or smokey quartz that has been heated to the required temperatures in order to bring about a change in the colour. True natural citrine tends to be light in colour though dark, well saturated stone can be found. Almost all heat treated citrines will have some degree of red or dark orange tint about them which can be quite rich and alluring in its own right. Light citrine can also be heated to improve the colour.

Citrine comes in a range of colour tones and associated trade names. The darkest, richest and most expensive is Madeira citrine which also used to be called "ox-blood" citrine once upon a time. There is Rio-Grande citrine, golden citrine, and others. You can see a
colour chart for citrine on this page. Citrine is a very popular jewelry stone and can be cut in virtually any design. Citrine is readily available in nice clean large sizes.
