Interesting ring that is probably glass or Smokey Quartz. Spectrum Unlimited sold these rings through e-tailers and retailers since 2000. We believe this ring is stainless steel which became part of their line in 2005. We are calling the glass or Smokey quartz color ?Cognac? because of the brown yet still translucent nature. Very stylish and because we purchased it as part of a larger lot, we can offer at a lower rate. Go check out some of the other Spectrum rings and you will understand what we mean. Will ship USPS first class with tracking free to winning buyer
