Raw Pink Oregon Sunstone Crystal Ring in Sterling Silver Sz 5 with Copper Schiller make a great Valentine's Day gift. Each sunstone is completely raw, just as found in nature, and handpicked for its unique sparkle and durability. Sunstones have a high "refractive index" and can be just as sparkly as diamonds. Originating in a basalt flow deep in the Oregon desert, these sunstones are formed differently than many low-temperature crystals. The tiny copper platelets in the stone will dazzle and draw you in.
