This mixed materials necklace by Roberto Coin uses black jade, green agate and diamonds (totalling .388ct), set in 18k rose gold. It’s a pretty alternative to some better known (and costlier) designer pieces, like the popular Van Cleef & Arpels Alhambra clover shape.

It measures 90 cm long, and closes with a lobster clasp. It’s available from Coin online for € 8.230.
