What on earth is druzy and what is druzy quartz and blue lace agate druzy? Merriam-Webster on-line does not recognize the word druzy and the word is not listed in the Fire Mountain Gems Encyclobeadia.
Druzy occurs when mineral deposits seep through stone cavities and crystallize within, and on the surface of, the stone. Quartz and agate stones fracture with the earth's pressure and allow crystalline structures to occur. Amethyst quartz is popular in jewelry. Geode slices and stalactite druzy reveal a core of druzy mineral deposits also. It is not so easy to find similar slices for earrings, but the fun task is finding two that are compatible.
The word druzy has a few spellings also--it can be druzy, drusy or drusie.
