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

A heavy flat base gives a four-prong head a broad, stable seat to solder down and a thicker wall of metal to hold prong geometry through setting and finishing. These round cast settings come in 14K yellow gold, 14K white gold, and platinum, each one cast by Victor-Joseph (Joseph VRT), a worldwide leader in quality precious metal findings, in the USA from 100% recycled gold and platinum.

Eleven stone sizes run from .25ct (4.0mm) to 3.0ct (9.0mm), giving a consistent foundation for solitaire and prong-set round brilliant work. Settings are sold by the piece, so only the sizes in hand need to be stocked.
