Drusy are these beautiful, glittering formations that are getting very popular in contemporary jewellery design right now, but what is it actually?

Many people think that ‘drusy’ is a specific gemstone, but it is rather the state of a gem than a specific stone. You will find amethyst drusy, uvarovite drusy, quartz drusy, pyrite drusy, onyx drusy etc. but also some man made drusy creations such as titanium drusy.

 Drusy  means “covered by a large number of  crystals”. The crystals can either appear on the surface of the mineral or are recessed into a crevice, both formations are called drusy.

The formation of drusy

When molten rock was being forced rapidly up to the surface, the heat and pressure changes caused gasses to expand and created cavities within solidifying rock. Later, water moved through the rock and deposited new minerals into these cavities. Cooling began to occur and the crystallization of these minerals formed on top of and inside the previously crystallized rock. This crystal formation is called Drusy.
