"Often rumoured, seldom seen" is a phrase that aptly describes Imperial Topaz. Despite the almost universal recognition of the term "Imperial Topaz," there is almost no additional information associated with this gemstone in the public arena: what is it? where it's from? what is it worth? In truth, while many have heard of Imperial Topaz, few have actually seen the gem and even fewer still own any. In actuality, there is very little of this gem material available on the world market at any given time. This gemstone is an exceptionally fine example that possesses the signature color balance of orange and pink that is the hallmark of this gem. It is in excellent condition as well as being an exceptional example of this seldom seen gemstone.
Measurements: 24.62 x 9.85 mm, 17.04 ct. Estimate: $32,000 - $35,000.
