chiral (hence optically active if not racemic) Location: World wide Rarity: Common Fun Fact: Quartz is not the only mineral composed of (SiO2) Silicon Dioxide
Those in relationships can benefit from the cooperation vibe coming from Hematite
An early use of this property of quartz crystals was in phonograph pickups

Labradorite Tumbled Stones - Medium 20 - 30 mm - 1 LB - Madagascar Wind Chimes chiral (hence optically active ifLABRADORITE Labradorite ((Ca,Na)(Al,Si)4O8), a feldspar mineral, is an intermediate to calcic member of the plagioclase series. It has an anorthite percentage (%An) of between 50 and 70. The specific gravity ranges from 2. 71 to 2. 74. The streak is white, like most silicates. The refractive index ranges from 1. 555 to 1. 575. Twinning is common. As with all plagioclase members the crystal system is triclinic and three directions of cleavage are
