Red-brown topaz is also common and found in Mexico and Utah, it makes a nice faceted stone, and some don't. Again it is not of high value. It is typically more expensive than citrene, and far less than morganite, or good golden beryl. The color is due to the presence of hydroxyl ions, and hence this variety is heat sensitive, and it usually contains numerous flaws. Preferred colors make this stone about the same in value as good aquamarine.
Pink topaz is fairly rare, but highly valued.
Green is another rare color, but highly valued. Although pink is occasionally found in jewelry, the green is very rarely found.
