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

Seat a round solitaire or accent stone in a low, clean-lined head at the bench. These die-struck 4-prong low base settings, the Victor 34V, are made in the USA from 100% recycled platinum by Victor-Joseph, and cover 23 calibrated round sizes from 1.0 mm (0.005 ct) through 8.0 mm (2.0 ct). Die-struck construction gives the precise, repeatable geometry professional jewelers rely on for fine solitaire and accent stone work. Sold by the piece.

Features

  • 4-prong low base design for a refined, classic profile
  • Die-struck construction for consistent detail and repeatable geometry
  • Made in the USA from 100% recycled platinum
  • 23 calibrated round sizes from 1.0 mm – 8.0 mm (0.005 ct – 2.0 ct)
  • Setting height, top width and bottom width listed for every size
  • Sold individually, so you order only the quantity the job needs
