This ring is one-of-a-kind. The stone is a rare seam agate that I found in the Yuba River of the Sierrra Mountains of California. I have never seen another one like it. The stone is white with both yellow and purple tones and is especially striking in sunlight. It has a slight orange glow depending on the light.
 
The ring is a mix sterling silver (.925) and fine silver (bezel), and is between sizes 8.5-9.
 
1 1/8" x 7/8"
 
Although it's the only one, a single pair of earrings from pieces of the same stone will be available soon!
