Description
London Blue Topaz :
is topaz stone that has a specific medium blue color. It’s darker than aquamarine or Swiss Blue Topaz, but lighter than what we normally look for in a blue sapphire. Topaz itself is a fluorinated aluminum silicate, and has a Mohs hardness of 8. This makes it harder than quartz, but not as hard as corundum (e.g. sapphire or ruby) or diamonds. It often occurs with quartz crystals.
