This striking and unusual stone lends itself to one of my swirled band ring settings. A square chunk of slate features a naturally occurring linear inclusion of chunky pyrite down the center--so cool. It is wrapped in a bezel of 22k gold and set on a swirled band of oxidized silver. Accents of gold complete the ring.
Measures a bit larger, but fits like a size 8 due to the width of the band.
