Wwake classic Opal and diamond earrings (pair)

I’m pairing down my jewelry collection to save for a trip to Iceland! I’ve worn these a bit, and the 10k butterfly backs show some discoloration, as well as one of the posts. My body chemistry does this unfortunately, even with 10k & 14k gold. They have been cleaned often in my ultrasonic cleaner and discoloration does not affect wearability. I purchased through my local jewelry store who carries WWake (the golden carrot in Charlotte) so they will come with a golden carrot box, not a wwake box. 14k solid recycled yellow gold 10k solid yellow gold butterfly earring back Earring Height 6mm Opal: Diameter 4mm, 0.15 cts, Australia origin Diamond: Diameter 1.5mm, 0.015 cts, reclaimed
