This lovely pair of earrings is featured with dark brown Australian Boulder Opals. This is a very pretty pair of opals with the center of the brown ironstone having blue and green flashes of opal. The sterling silver has been handstamped for interesting texture around the gemstone. Balls of 18K gold surround the Boulder Opal and above it is 23.5K gold, done with the Keum Boo process of fusing it to the silver.
The pieces have been oxidized (blackened) to bring out the design. The back has been stamped with the hallmark and maker's mark.
The earrings measure 1-7/8-inches from top to bottom and 1-inch wide.
