Premier Designs Pendant with Removable Reddish-Brown Gem

Premier Designs Pendant with Removable Reddish-Brown Gem; I don’t know much about premier designs as a brand, but I found this at a thrift store and decided to pick it up- it looks somewhat vintage/mid-evil in style and could make a good gift. The pendant appears just as pictured- the stone itself seems to be in good shape and I am thinking it resembles Tigers Eye, but I’m not certain!
