Opals sometimes get a bad rep, but I personally think they are possibly THE most stunning natural stone. The natural iridescence that they give off is unparalleled. From different angles the same stone can look completely different. The colours within colours is simply mind blowing. For the Sweetest Thing necklace I paired blue tanzanite mini facetted coins with some gorgeous opal rondelles and the result is perfection. All metal detailing is in sterling silver.
