  • Patent number: 4118948
    Abstract: A finger ring comprised of two individually molded metal members, namely, a ring base and a ring cap joined together. The ring base is a molded circular band of metal which comprises the larger portion of the ring. The ring cap is a molded arcuate shaped metal member, slightly larger than a semi-circle which interlocks over the upper portion of the ring base. The bimetallic construction reduces the amount of precious metal required, thereby reducing the cost of construction without altering the aesthetic appearance or durability of the ring.
