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 threaded post and screw nut close an earring securely enough for fine jewelry production and for repair work where a friction back has already failed. Each piece is one threaded screwpost paired with one two-hole screw ear nut from WR Cobb, made in the USA from 100% recycled precious metal and offered in 14K yellow, 14K white, 14K pink, 18K yellow, 18K white, and platinum.

The post measures 1.04mm (.041") in diameter and 11.1mm (.437") long. The nut matches it with a 1.04mm (.041") hole in a body of 5.75mm outside diameter. Sold per piece as one post and one nut, so order two pieces for a complete pair.

Features

  • Threaded screwpost pairs with a two-hole screw ear nut for a secure, polished closure
  • Post diameter 1.04mm (.041") and post length 11.1mm (.437")
  • Nut outside diameter 5.75mm with a matching 1.04mm (.041") hole

  • Manufactured to ISO 14001:2015 Environmental and ISO 9001:2015 Quality Management System certified standards
  • Six precious metal options: 14K yellow, 14K white, 14K pink, 18K yellow, 18K white, and platinum
