During the war, many metals were restricted but surprisingly not silver. Companies such as Reja was forced to use silver in their pieces which increased the costs making vintage Reja brooches highly sought after . Vermeil is sterling silver coated with gold. To be considered Vermeil, the gold must be at least 10 carat (42%) and be at least 2.5 micrometres thick. 

The Reja Jewelry Co. was founded by Sol Finkelstein in 1939, however, initially it traded under the name of Deja Costume Jewelry Inc. The company was a boutique manufacturer of costume jewellery selling through smaller gift shops and jewellery stores. The name change was a result of a legal dispute with DuJay, Inc. over trademark infringement. Vintage Reja jewellery/jewelry is usually marked with a stamped "Reja" but is quite scarce when compared to many of the other mid-20th century American costume jewellery manufacturers. Reja ceased ongoing operations in 1962 making Reja vintage jewellery/jewelry highly valuable.
