Other more intense cleaning methods could damage the gem. When cleaning an opal, the safest method is to gently wipe it down with lukewarm, soapy water. It’s recommended that you store jewelry featuring opals by themselves away from other jewels, as diamonds, rubies, sapphires, emeralds, and other harder stones can scratch this October birthstone.

While white opals are the most common and popular, opals have hues ranging across the whole color spectrum including black opals, pearlescent pinks, pale greens, and more. Opals are popularly known for their milky, rainbow-colored glow and fire.
