Appearence:
Topaz crystals grow in
the orthorhombic shape and are usually terminated at only one end. Yellow
topaz is sometimes called "precious topaz" to distinguish it from the names
"gold" and "madeiria topaz", which are in fact citrine (quartz). Yellow
topaz is sometimes heat treated to make it look pink. The term "imperial
topaz" is used by ethical jewelers to refer to topaz that is reddish orange
of medium tone and higher saturation.
Something
Extra:
Although Topaz of any
color is the birthstone for November, other Gemstones have also been used
as a November birthstone
substitute. Previously Yellow was the dominant color used in birthstone
jewelry. But many of
the stones used by manufacturers in these inexpensive settings were actually
Citrine, a Yellow variety
of Quartz. Smoky Quartz was also called Smoky "Topaz" by many
unscrupulous persons
and unknowing jewelers in an attempt to create more sales in this birth
month.
