About the Item

This rare 12.61 Ct Australian black boulder opal was mined by Sue Cooper at her Yaraka opal mine in western Queensland, Australia in 2021. Sue processed the rough opal herself and cut into into a classic rectangle shape. We love how bright the green and blue colors are against the black body tone / background. The opal's size of 18.1 x 14.7 mm make it perfect to wear as a statement ring.
