May 2020 Newsletter: Rare Imperial Topaz

Topaz is a gem with excellent hardness -- 8.0 on the Mohs scale -- but most topaz found in nature is an uninspiring color, either colorless or an insipid yellow or brown. Some of this common topaz can be irradiated and heated to produce the cheap blue topaz that is ubiquitous in commercial jewelry.
The only topaz that has real value in the gems world is precious topaz, known in the trade as Imperial Topaz. Imperial Topaz is golden to golden-orange to orange, pink, pinkish-red or violet in color. It is a rare stone that is suitable for all kinds of jewelery.
The Ouro Prêto area in Minas Gerais is the main source of natural Imperial Topaz. The two large-scale mines of Capão and Vermelhão produce most of the Imperial Topaz on the market today but there are also several small-scale mines operated by independent miners
It is essential that the color of Imperial Topaz be completely natural. Some of the imperial topaz colors can be simulated by irradiating colorless or weakly colored topaz. You will see these treated stones selling for a few dollars a carat from auction sites. Unfortunately the color tends to fade quickly when exposed to sunlight, so the fake imperial topaz is a poor value even at its modest price.
High quality topaz is typically very clean, so the main grading distinctions for imperial topaz are by color (and, to some degree, by cut).
The least expensive Imperial Topaz color is the bronze or golden hue. The golden-orange tends to be more expensive, while the golden-orange with red dichroism enters the realm of the rare and expensive. If your Imperial Topaz displays a red flash, then you know you have a valuable stone.
Any Imperial Topaz with a pinkish hue -- even a pinkish secondary -- is especially valuable, and an orange-pink or reddish-pink is extremely rare. A true pink-red or red topaz is the ultimate rarity.
We have a substantial collection of imperial topaz in all grades. In this month's notable gems we feature a recent addition to our collection -- a rare pink-orange with red flash. This is a very fine specimen for the Imperial Topaz collector or for a special piece of jewelry.
