Rainbow Moonstone Tumbled Gemstone

Relatively soft with perfect cleavage; it can chip or scratch. Avoid ultrasonic cleaners, harsh chemicals, salt, and prolonged soaking. Clean gently and store separately from harder stones.

Fine Moonstone was first prized as adularia, a variety of orthoclase feldspar named after Mount Adular in the Swiss Alps, one of the earliest known sources of gem-quality material. Its signature glow, called adularescence, is created by light scattering between microscopic alternating layers of orthoclase and albite feldspar within the stone.

Moonstone is a potassium-sodium aluminium silicate of the feldspar group, typically the adularia variety of orthoclase. Its billowing blue-to-white sheen, known as adularescence or schiller, results from the scattering of light across thin, layered feldspar intergrowths. It crystallises in the monoclinic system, shows perfect cleavage, and rates 6 to 6.5 on the Mohs scale.

• Ancient Romans believed Moonstone was born from solidified rays of the moon and held it sacred to the lunar goddess Diana.
• In Hindu tradition, Moonstone is a sacred dream stone said to be made of frozen moonlight, bringing sweet dreams and good fortune to those who wear it.
• Travelers of antiquity carried Moonstone as a talisman for safe passage on night journeys and across water, earning it the name the Traveler's Stone.
