Druzy (sometimes spelled druse, or drusy) is a type of geological formation that occurs when small crystal formations occur on the surface of a stone. Druzy does not form on just agate, either-- the possibilities for stones hosting druzy are boundless, which is why you can see druzy growing on garnetschrysocollamalachite and more. It can even grow on the surface of old seashells, providing incredibly unique specimens. This crystalation process occurs over millions of years, when water brings minerals to a stone’s surface, forming tiny crystals that are attached to another rock formation. The end effect can be sparse, or provide an incredibly dense, sparkly effect. 


You may wonder what the difference between druzy and geodes is. But there is no difference-- druzy is what grows on the inside of geodes. These crystals are usually given the time to grow into larger crystals. However, the term “geode” is usually only used when referring to the crystal structures that grow on the inside of enclosed minerals, but druzy can be exposed. Whereas geodes are geological surprises-- druzy can typically be found growing on the final layer of most rocks introduced to water at some point. 


Druzy can come in a variety of colors depending on the stone it grows from. In the case of druzy agate (the kind of druzy we source at Dakota Stones), the agate provides the perfect source for an amazingly customizable stone. Natural agate is a lightly colored stone that typically comes in muted tones. Unprocessed druzy agate can look unassuming at a first glance, but when the tiny druzy crystals catch the light, it can pack an impressive punch. 


When paired with metallic finishes and facets, the result can be pretty flashy. It’s no wonder druzy tends to have a polarizing effect on people. Whatever your opinion on druzy is, however, these stones need no intricate design to speak for themselves. They are inexpensive, and come in a wide variety of colors, making them accessible to any designer working with all kinds of different stones. For a sharp design, you can try pairing rainbow druzy agate with onyx or black spinel. If you like bright, glittery designs, pair some bright blue or purple dyed stones with faceted hematite to lean on their metallic look. For a more subtle, soft design, try pairing white or untreated stones with mother of pearl or zircon.
