Information on gemstones
Smoky quartz is a variety of quartz ranging from very pale yellowish smoky color to nearly black.
Smoky quartz is believed to be created from clear quartz through very long time exposure (thousands or even millions of years) to very small amount of natural radiation found in some rocks and stones.
Smoky quartz is a beautiful crystal with a very affordable price and is getting more and more popular because of that.
Sometimes there are rutile inclusions in smoky quartz and this variety is called rutilated smoky quartz and is much rarer than normal smoky quartz.
Hardness of smoky quartz on Mohs scale is 7.
