Loved it so much we bought two!
I love it! Was exactly what I wanted when I ordered it!







This Tungsten Black Sand and Fire Opal Ring is built with material sourced from Iceland’s world-famous Reynisfjara Black Sand Beach, known for its towering basalt stacks and roaring Atlantic waves. The deep black sand and fiery opal fragments are hand-harvested and set in place by hand, sealed with a durable epoxy for lasting strength and shine. Each ring is made to handle real wear while showcasing the beauty of one of the world’s most striking landscapes.
What Makes Each Ring Unique
Every inlay is built by hand, blending Icelandic black sand with vivid flashes of fire opal. The result is a one-of-a-kind contrast between dark grit and natural light.
Materials
Crafted from solid tungsten for unmatched durability and scratch resistance. The inlay combines genuine Reynisfjara black sand and fire opal, sealed in protective epoxy that can be re-polished as needed.

The most accurate way to find your ring size is by using one of our free ring sizing kits! These kits are a close match to all of the rings we make. Your fingers can change size throughout the day so make sure to try them on a few different times before deciding your size. You can even wear them around for a couple of days to make sure they’re the perfect fit.
You can also visit your local jewelry store to find your ring size. We recommend visiting two different stores to makes sure your sizing is consistent using a comfort fit band in the same width you plan to order.
Avoid using string or a fabric tape measure to measure your ring size, or the common zip tie measuring devices. It’s very important to use the same width ring sizer as the ring you intend to purchase. Learn more about common mistakes or ring sizing by watching our video here.
