05 · May · EmeraldRepresentative photograph. Natural stones vary in colour and inclusions from piece to piece — yours will not be identical to this one.

Emerald Stud Pair 4 mm — 9ct Gold
Matched natural emeralds, fracture-filled, in hallmarked 9ct gold.
Coloured stones are natural material. Colour, tone, inclusion pattern and — on cabochons and uncut pieces — outline and size differ from one to the next. Two pieces of the same reference will not be identical.

About this piece
Matched for tone across the pair, which is harder with emerald than with most species because colour and clarity vary so widely within a single parcel. Both stones are fracture-filled. Solid 9ct gold settings and posts, hallmarked at 1.5 g.
Total carat weight across all 2 stones: 0.64 ct. The wear grade shown for the piece as a whole is occasional, because a piece is only as forgiving as its softest stone.
