HOW TO CHOOSE

It is important to choose a gemstone for its beauty, not its name. Just because Imperial topaz prices are about ten times that of citrine, choosing an Imperial topaz of accessory quality is meaningless--- at that level, there is almost no difference between the two. Jewelry -quality Imperial topaz, however, is exceptional, and can easily be distinguished from citrine, especially under incandescent light.

A simple pendant set with a gem-quality Imperial topaz weighing a bout three carats can be purchased in the$2,500 to $4,000 range. It is a highly recommended gemstone for those considering what to buy for their next jewelry purchase.

The value of a three-carat-size Imperial topaz of jewelry quality is approximately US $1,200 for the stone alone.
