This necklace combines 4 boulder opal slabs with copper colored freshwater pearl sticks and other pearl shapes. I go for the wilder shapes and colors. The opals have a distinct blue cast, and I also used kyanite in rough blue sticks. Also you will see smoky quartz points copper and other spacer beads. The clasp and chain is copper too.
I call these chunky, irregular uncommon pearls necklaces subversive pearls - they are not your grandmother's pearls for sure!
