Garnet and Onyx Necklace – Argentium Silver Geometric Pendant
Description
This Garnet and Onyx Geometric Pendant combines structure and contrast in solid Argentium silver. I paired a round cabochon Garnet with deep clarity and a pure black oval Onyx to create balance through shape and tone. The silver framework ties both stones together in a bold, clean design.
Design & Feel
The round Garnet glows with warm red light, while the Onyx provides a calm, dark reflection beneath it. Their geometric arrangement gives the pendant a sense of symmetry and strength. It’s a versatile piece — bold enough to wear long as a statement or short for a modern accent.
Argentium Heat & Finish
I heat-treat the pendant to form the germanium oxide layer that strengthens Argentium silver and slows tarnish. The high points are polished to a smooth sheen, while the recessed areas retain a subtle matte texture for contrast.
