Blue Topaz
According to a well-known gem and jewelry industry magazine, “Colored Stone”, since the early 2000s, blue topaz has become the second most popular gemstone in the world (sapphire is consistently number one). Topaz popularity is certainly not surprising. Topaz is a very hard material – 8 on the Mohs hardness scale – and blue topaz is a very pretty stone that is available in a wide range of vivid hues with a striking vitreous luster. It is also a very affordable gem when compared to the price per carat of similar colored gemstones such as aquamarine.
At the same time, blue topaz is a gem that is not well understood by many buyers and some recent controversy in the USA has led some buyers to rethink their blue topaz purchases. In this case, access to the correct information can help blue topaz customers make informed decisions about whether to buy blue topaz or not. There are two important things to know about blue topaz. The first thing is that while topaz is very hard, it is not the most durable gemstone. That’s because it has perfect cleavage, a property it shares with diamond. That means it can be chipped or split by a sharp blow, so it should be protected from hard knocks.
