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 positive locking earring back replaces a friction clutch when a finished earring needs to stay put on the ear until it is deliberately released.

These Original Guardian backs from WR Cobb, also known as Guardian Ear Nuts or Safety Earring Backs, use straight, ridged trigger tabs that lock onto a matching post groove and release only when both side tabs are pressed at the same time. Each clutch measures 6.1 mm (0.240") across and fits a 0.89 mm (0.035") post. They are sold individually, so order two for a pair, in 14K yellow, 14K white, 18K yellow and 18K white gold and in platinum, all made in the USA from 100% recycled precious metal.

Features

  • Original Guardian design with straight, ridged trigger tabs
  • Positive-lock mechanism engages the post groove and releases only when both tabs are pressed
  • Made in the USA using 100% recycled gold and platinum
  • ISO 14001:2015 and ISO 9001:2015 certified manufacturing
  • Sold individually; order two for a pair
