About the Item

Offered Oval Mixed cut Natural Gemstone Flawless London Blue Topaz 21.23 ct. It's 'AAA' Quality & Loop Clean Gemstone. Transparent. Ideal for ring of pendant! Dimensions:13.08mm*18.35mm*14.59mm Origin : Brazil Treatment: heated London Blue topaz has a fair bit of mystery and intrigue surrounding it. The stone has a specific hue of blue that makes it look almost inky and sets it apart from regular blue topaz, which is also known as Swiss Blue topaz. It’s often confused with blue sapphires, but the two are actually quite different. By definition, London Blue topaz is a topaz stone that has a very specific, inky shade of blue. It’s darker than regular topaz but lighter than a sapphire. In fact, the color is best described as a halfway point between the two. The topaz stone is composed of fluorinated aluminum silicate. It measures in with a hardness of eight on the Mohs scale, which means that it is harder than quartz although it often grows alongside it. While harder than quartz, London Blue topaz is not as hard as sapphires, rubies or diamonds. The latter three are classified as gemstones, while topaz is classified as a mineral. At the moment, London Blue topaz is highly favored within the market. This has elevated its price slightly over that of regular blue topaz, but not by any amount that’s too significant in value. They do tend to add a sense of glamour to pieces of jewelry and outfits but can fetch as low as $10 to $30 per carat.
