What is "diamond's"

Diamond's was a department store based in Phoenix, Arizona.

Originally named The Boston Store, it was founded in 1897 by Nathan and Issac Diamond, Jewish immigrants who had earlier begun a dry-goods mercantile in El Paso. Consisting of one store in downtown Phoenix, it was renamed Diamond's in 1947 in honor of the store's 50th anniversary. Diamond's had expanded to twelve stores throughout the Southwest when in 1984 then owner, Dayton-Hudson Corporation, sold the chain to Dillard's.
