At the time, Uncas was the largest ring manufacturer in the United States and made both costume and precious metal rings. All of the Uncas rings I have listed were purchased directly from the factory and have had just one owner. None have been rolling around in estate sales or thrift stores. They have been stored properly in a climate controlled, smoke free environment. I will do my best to pinpoint the era of each ring, but some did span 2 or 3 decades due to the popularity of the style. This one is 1960s Fast Shipping Daily from Florida
