Opal earrings. ^ ^ I love opals and own many, and these are unused. The base metal is K18 yellow gold. The play-of-color in the stones is beautiful, although it doesn't show well in the photos. <Size> Length x Width: Approximately 7mm x 5mm *If you need the box and outer box in the image, they are available for an additional 500 yen. Please let me know in the comments before purchasing.
