This calibrated round “Opal” druzy quartz cabochon features a "window" cut-out that reveals tiny sparkling crystals—it’s coated with titanium to bring out a consistent, iridescent color. Every cut-out is unique and no two stones are exactly alike. Highlight its vibrant colors by setting it in a simple pendant mounting or combine it with complementary-color stones to create more complex necklace designs and matched sets, including rings and bracelets.
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.
