Rare natural sphene ring. Size: US 5.5 - 5.75 Silver with gold color plating. Vibrant yellow stone. Sparkling brilliantly due to sphene's high refractive index. As seen on the right side of the image, there is a part where the reflection is refracted, so it is offered at a reduced price. However, that part also sparkles beautifully when illuminated. The size is about 8 mm x 6 mm, giving it an elegant presence.
