These pretty earrings by Monica Vinader look more expensive than they are. This pair is made with amazonite (other stones are available) and 18k rose gold plated sterling silver.
Vinader’s site notes, “Inspired by sea-worn treasures and the glamour of southern Italy. Hand cut gemstones mean these earrings are slightly different each time, but gorgeous 100 percent of the time. Wear alone or add to a stack.”
These are priced at USD$150.
