About this piece
Solid 9ct yellow gold settings, posts and backs. At 1.4 g the pair is over the 1 g statutory exemption for gold, so both earrings carry a UK hallmark. Gold posts rather than plated ones matter here: plating on a post wears through against the piercing channel within months.
Total carat weight across all 2 stones: 2.00 ct. The wear grade shown for the piece as a whole is occasional, because a piece is only as forgiving as its softest stone.
