Description

Made with certified recycled precious metal. Our silver, gold and platinum is refined from certified recycled content rather than newly mined ore, through refiners audited by outside parties. How we source our metal

Set a round stone into a finished earring with these cast 3-prong cocktail mountings, also known as martini earrings. Each mounting arrives with a screwpost and nut for a refined, professional finish, and the range covers nine stone sizes from 4.0mm to 8.0mm, holding stones of roughly .25ct to 2.0ct in five precious metal types.

Cast construction keeps quality and detail consistent across the range, which makes these a versatile staple for fine jewelry production and custom work. Available in platinum, 18K yellow, 18K white, 14K yellow and 14K white gold. Sold by the piece, with one screwpost and one nut per mounting; order 2 for a pair.
