Item Description

Swiss Blue Topaz goes back several decades, where colorless Topaz was irradiated in order to turn it blue. You'll find various shades of blue on the market, but the bright blue gems are still the most popular among dealers and jewelry. For reference, the irradiation method is well known in the gem trade and is not at all frowned upon, provided that people KNOW that they're buying a treated gem. There are actually very few gems in the world with this color and this gem has a great blue hue. This stone is virtually eye clean with an "Oval Brilliant" cut.
