Quartz

Quartz is one of the most important minerals on earth and makes up one of the most popular gemstone groups. It has been used for centuries in the creation of jewelry and ornamental objects. There are two main varieties of quartz: macrocrystalline and cryptocrystalline. Macrocrystalline quartz includes amethyst, aventurine, rock crystal, blue quartz, citrine, prasiolite, smoky quartz, and rose quartz. Cryptocrystalline quartz includes a wide variety of gemstones, including agate, chrysoprase, bloodstone, jasper and carnelian. Rock crystal and smoky quartz were once used for crystal balls by fortune tellers. Many healing powers are attributed to quartz, with help for everything from headaches (amethyst, rock crystal) to sciatica (citrine, rose quartz, tiger's eye).

Colors:	Quartz gemstones can be found in just about any color imaginable.
Shapes:	Usually cut as brilliant rounds, quartz is a versatile material that can be cut and carved into many shapes and sizes.
Origin:	Quartz gemstones are found in locations all around the world; it is the second most abundant mineral found in Earth's continental crust.
Care:	To clean, simply use plain water and a mild soap or detergent if needed. Wipe your stones using a soft cloth and be sure to rinse well to remove any soapy residue.
