Virtually all Blue Topaz on the market today is created by irradiating and then heating colorless topaz. The process is permanent and yields the beautiful blue shades ranging from the deepest intensely smoldering London Blue Topaz, to the lighter shades of Swiss Blue Topaz and Sky Blue Topaz. Here you will find Blue Topaz Beads incuding Briolettes, Cushion Cut and Rondelles in AA to AAA quality.
