Rutilated Quartz 4mm top only internally threaded

"Rutilated quartz" is a type of quartz crystal that contains needle-like inclusions of rutile, a mineral composed primarily of titanium dioxide. These needle-like inclusions can vary in color, including gold, silver, copper, or black, and they often form fascinating patterns within the quartz crystal. Rutilated quartz is valued for its unique appearance, as well as for its metaphysical properties. It is believed to have powerful energy, often associated with cleansing and purifying the aura, promoting spiritual growth, and enhancing mental clarity. Many people use rutilated quartz in meditation practices or as a decorative stone.  Item Details •Sold individually • Materials - ASTM F136 Titanium, Semi Precious stone • TOP ONLY ( SEE LINK FOR BACKS) • Threaded internally 0.9mm screw (16g) 1.2mm thread (14g most dermal) • Size 4mm cabochon stone
