Druzy or sometimes referred to drusy, druse, or druze or aura quartz is most well known as versions of agate and quartz. Quartz is one of my favorite stones to work with because it is so versatile and comes in so many difference types, shapes, and colors. Whereas agate is actually a form of microcrystalline quartz itself that are formed in banded layers. Because of the unique colors and layers it forms, no two agate stones will ever be identical. Both agate and quartz stones can develop the layer of druzy crystallization. We here at Gem Lounge Jewelry prefer to use druzy quartz in our designs and these stones are very durable and strong.
