Quartz, which consists of silica, or silicon dioxide (SiO2), has great economic importance. Many varieties are gemstones, including amethyst, citrine, smoky quartz, and rose quartz. Sandstone, composed mainly of quartz, is an important building stone. Large amounts of quartz sand (or silica sand) are used in the manufacture of glass and ceramics and for molds in metal casting. Crushed quartz is used as an abrasive in sandpaper; silica sand is employed in sandblasting; and sandstone is used whole to make whetstones, millstones, and grindstones.

quartz diorite: (Jeoloji) Quartz diorite is an igneous, plutonic (intrusive) rock, of felsic composition, with phaneritic texture. Feldspar is present as plagioclase (typically oligoclase or andesine) with 10% or less potassium feldspar. Quartz is present at between 5 to 20% of the rock. Biotite, amphiboles and pyroxenes are common dark accessory minerals
quartz-halogen lamp: A quartz halogen lamp also called tungsten-halogen lamp, the halogen lamp or the quartz-iodine lamp is an incandescent lamp wherein a tungsten filament is sealed into a small transparent envelope filled with a halogen gas such as iodine or bromine. The halogen lamp can operate its filament at a higher temperature than in a standard vacuum or inert-gas filled lamp, without loss of operating life. This gives it a slightly higher efficiency than standard incandescent lamps
quartz-iodine lamp: A quartz iodine lamp also called tungsten-halogen lamp, the halogen lamp or the quartz-halogen lamp is an incandescent lamp wherein a tungsten filament is sealed into a small transparent envelope filled with a halogen gas such as iodine or bromine. The halogen lamp can operate its filament at a higher temperature than in a standard vacuum or inert-gas filled lamp, without loss of operating life. This gives it a slightly higher efficiency than standard incandescent lamps

rose quartz: A pinkish variety of the mineral quartz, used as a gemstone or as an ornamental stone. Translucent, coarse-grained variety of the silica mineral quartz found in pegmatites. Rose quartz is valued for its pale to rich pink colour, which is due to very small amounts of titanium. It has been carved since early times and has been faceted to provide gems of good brilliance. Its milky aspect is attributed to tiny, needlelike inclusions of rutile, which, when oriented, give the polished stone an asterism (optical phenomenon of a star-shaped figure) like that found in sapphire, but not as sharp or intense. Rose quartz occurs in Brazil, Madagascar, Sweden, Namibia, California, and Maine, among other sites
rose quartz: Named for its color, it is said that rose quartz should only be given as a gift to one's true love See Quartz A R T Precious & Collectible Jewelry
rose quartz: Emotional balance, Self love, friendship Very good for expressing and soothing emotions Try to find undyed rose quartz I find that gold doesn't mix with rose quartz Vibrations of universal love & inner serenity PLANET: Venus
smoky quartz: A transparent or semitransparent brown or gray to nearly black variety of quartz, used as a gemstone. Also called cairngorm. Common, coarse-grained variety of quartz that ranges in colour from nearly black through smoky brown. No distinct boundary exists between smoky and colourless quartz. Its abundance causes it to be worth considerably less than either amethyst or citrine. Heating bleaches the stone, the colour sometimes passing through yellow; these yellow pieces are often sold as citrine
vein quartz: Quartz occurring as gangue in a vein
