Blue Titanium tumbles are a stunning and eye-catching piece — created by coating natural Quartz crystals with a thin layer of titanium through a vapour deposition process, these tumbles have a deep, vivid blue iridescence that is unlike anything found in natural stones. The colour is permanent and won't fade. Titanium-coated crystals are beloved for their extraordinary visual impact and are widely used in crystal healing for their reported ability to amplify the energy of the base crystal. At $3 these tumbles are an extremely accessible and beautiful piece for any collection or display.
