Whether you read deeply into the mystical meanings behind certain gems (guilty astrology nerd present!) or choose your baubles based on looks alone, the opal is definitely not one to be left out of your jewelry repertoire.

And, the opal carries symbolic meanings that hark back to ancient times — it has long been considered a talisman of loyalty and faithfulness, a repeller of evil, and a protector of eyesight.
