Phenomenal Quartz

When thinking about quartz, the first thing that comes to mind is amethyst, rose quartz or citrine. But did you know that quartz also has some phenomenal varieties that are not as well known? Today I will discuss drusy, rutilated and aventurine quartz.


drusy quartzDrusy Quartz: Essentially a geode that has been carved to wear in a piece of jewelry, drusy quartz is a stone that has tiny quartz crystals that have formed on top of a host rock (usually quartz or chalcedony). Drusies form when ground water forces dissolved silica crystals into the porous areas of an already formed rock. Rapid cooling occurs which causes the formation of tiny quartz crystals. The crystals look like tiny bits of salt or sugar covering the surface of the host rock. Drusy is believed to be associated with peace, tranquility, patience, intuition, unconditional love and even aid in the relief of ulcers and arthritis.  





 Rutilated Quartz: Also known in the gemology world as sagenitic quartz, rutilated quartz is a colorless piece of rock crystal quartz that is filled with beautiful rutile inclusions. The rutile needles are often large and beautiful and in unusual shapes and textures contributing to the beauty and allure of the gemstone. The rutile needles can be reddish, golden, greenish, silvery or grey with golden as the most popular. There are not many historical records concerning rutilated quartz, but a few documents have dated it back to early Roman and Greek times. It has also been recorded that French doctors used to prescribe it to cure bronchitis.


adventurine quartzAventurine Quartz: Generally green in color, aventurine quartz is a clear piece of rock crystal that is heavily included with mica inclusions that, not only make the stone appear green, but also gives it a metallic sheen called Aventurescence. The phenomenon of Aventurescence ranges in intensity from weak to intense. This depends on the amount and size of the metallic inclusions. Aventurine is known to be a stone of luck. It is known to ease anxiety and emotion and it will help one to make choices from the heart.


We have beautiful specimens of both drusy and rutilated quartz that we just bought from the jewelry show. Stop in any time to see these phenomenal quartz varieties in person.
