What exactly is London Blue Topaz?
London Blue Topaz is a topaz stone with a particular medium blue hue. It’s deeper than aquamarine or Swiss Blue Topaz, but lighter than what we’d expect from a blue sapphire. Topaz is a fluorinated aluminum silicate with a hardness of 8 on the Mohs scale. It is therefore tougher than quartz but not as hard as corundum (such as sapphire or ruby) or diamonds. It is common in quartz crystals.
