Blue topaz is perhaps the most famous of topaz pendants, but it is not the only shade of blue known by name. Blue topaz is a sky blue color, while London blue topaz is a silvery color of blue: like frozen glacier water. They are both equally as beautiful, but very different. We cherish both colors and try to keep an abundance of each in stock. Sift our selection and see if one of them does not put a sparkle in your eye.
