THE BEST EARRING CLOSURE

The Rimlock earring back consists of a French butterfly clasp with two small plates. Once closed, these plates grip the piercing post, providing the extreme security that the most valuable earrings require.

To remove the back, firm pressure must be applied to the side triggers.

These triggers feature a double-grooved post, ensuring a truly secure closure. That’s why Rimlock is the ideal back for diamond earrings or any high-value jewelry.

  • Made from traceable gold according to the RJC system
  • Strong, secure, and durable
  • Tested over 20,000 times for tensile strength and durability
  • Surface wear test (salt spray test)

Rimlock is a high-quality earring back, designed by Quadrifoglio after years of research and product development.

A unique solution for high-end diamond jewelry earrings with significant carat weight.
