To see a world in a grain of sand and heaven in a wild flower, hold infinity in the palm of your hand and eternity in an hour. -William Blake. Your spirituality is on display with Smoky Quartz infinity jewelry. Brown gemstones are gaining in popularity and smoky quartz is an affordable choice. A smoky quartz ring goes well with autumn colors and evening wear. Once considered more valuable than diamonds, a peridot ring is a must have. This "gem of the sun" is the birthstone of August and is a beautiful match for the lush green tapestry of late summer.
