The term 'druzy' (or drusy) refers to tiny quartz crystals that are formed inside or on the surface of other stones when water containing silica particles is forced into a fissure or porous area of a rock and rapidly cools there. The clear crystals often form on top of previously deposited minerals, which give the particles their color. The crystals create a glittering effect as they reflect light from their many facets. Druzy stones are inexpensive and easy to cut into a variety of shapes?offering a great deal of color and light-play for a very affordable cost. Rio Grande's calibrated cabochons are calibrated to fit Rio Grande's corresponding size bezel cups, so you know the size you buy will fit properly every single time.
