Microcrystalline (or cryptocrystalline) quartz generally refers to gems in the “chalcedony” family. If you hear “quartz variety,” it’s usually macrocrystalline. Macrocrystalline quartz stones have larger, individual crystals that you can see without magnification. When categorizing the dozens of quartz varieties, the main types (or families) of quartz are macrocrystalline and microcrystalline. By the end, you’ll be able to start identifying different types of quartz gemstones and become a savvy quartz shopper!įirst, let’s go over the basics: what are the main types of quartz?
