Silver Ring

The stone shifts from orange to green to deep red, like a sunset captured in a dark pool.

This ring is fire agate, gold and sterling silver. Fire agate is a form of chalcedony whose thin layers of iron oxide scatter light into iridescent color, and each stone is cut to follow those layers. Here a large pear-shaped cabochon glows in rust, flame orange and green. It sits in a bezel built up from irregular flakes of yellow gold over silver, giving a rough, nugget-like texture. The gold patches continue down the shoulders, with silver showing between them, and the band at the back is plain silver. It is 1 inch long, 0.25 deep and 2.5 high.

A fire that will never need tending.
