Founded in New York in 1943 by Louis Kramer and his brothers Morris and Harry, Kramer Jewelry Creations became known for its elaborate costume jewelry, particularly its sparkling rhinestone designs. The company produced everything from delicate floral pieces to extravagant statement necklaces, earrings, and brooches, often incorporating Austrian crystals, colorful glass stones, and intricate metalwork. During the 1950s, Kramer also manufactured costume jewelry for Christian Dior under the Kramer for Dior name. The company remained active until approximately 1980, and its vintage designs are prized by collectors for their craftsmanship and mid-century glamour.
