Vintage 1970's Karen Brent Adjustable Size Cocktail Ring.

Limited information is available on this brand, but I did find the following write up. "The history of Karen Brent costume jewelry brand is shrouded in mystery. No catalogs, patents, or trademark data banks mention this brand or company. According to scarce sources, jewelry was produced for a short time, around the 1970s, in Ontario, Canada. Rare to find, jewelry of this brand demonstrates classic style, exquisite handicraft and filigree design. The materials used to create these jewelry are gold and copper tone alloys, superb crystals, imitation pearls and rhinestones. The marking on the back side of each item includes “Karen Brent” in stylized script, on a rectangular base with a copyright mark." This piece is in very good condition. The size is adjustable to fit any finger. Comes with original box, which is rare!
