Tiffany Stone

Tiffany Stone is a rare type of rock that's made up of a number of different minerals but it's not a mineral in its own right. To be precise tiffany stone is a mineralized nodule that can only be found in one specific area of Western Utah in the USA. The nodules were once impregnated by ground water that was rich in natural minerals including quartz and fluorite and along with manganese oxide, they give Tiffany Stone its striking colour.

This popular lapidary material is often referred to as bertrandite which is not accurate, although it is present in tiffany stone the are two different materials.  The mineral bertrandite is a primary source of beryllium hence the vast majority of tiffany stone is crushed up in order to extract this rare and highly sought after chemical element.

Despite extensive research we cannot find any factual evidence to explain where the name tiffany stone came from and although many articles online state that it's linked to tiffany glass, there is absolutely no evidence to support that.  Tiffany stone is also sometimes called ice cream opal and opalized fluorite and the latter from a geological perspective is a more precise description of what it actually is.

Tiffany Stone is a trade name which probably came about purely by chance when it was casually named after having first been discovered. As it gained popularity the name is likely to have stuck and once photos and articles started appearing online, it would have been too late to re-name it.  One thing that's known for certain is that the deposit where tiffany stone is found is no longer open or being mined so existing stocks are gradually drying up.

Graded 4 on Mohs scale of mineral hardness means tiffany stone is relatively soft so must be handled carefully but its a popular stone that's highly sought after for polishing into cabochons and its striking colour and markings make it a great choice for use in ladies jewellery.
