Calvaire, Inc. was founded by Ray Calish and his wife in the early 1920s, as an importers of costume jewelry. Known for their use of high quality materials and excellent craftsmanship.
Before WWII owners traveled to Europe to purchase jewelry from different manufacturers, having their company name imprinted on the pieces. Most was probably purchased in France. During WWII they purchased jewelry in the United States.
Probably ceased operations in the mid 1950s. Pot metal jewelry was signed on a plaque with the "C" extending beyond the "al" in Calvaire. Sterling jewelry (produced during World War II) and stamped jewelry was impressed with "Sterling" and Calvaire in block letters.
According to James Katz, Calvaire jewelry is so rare, that any piece may be a one chance in a life-time to purchase.
