In 1943, Louis Kramer opened his business Kramer Jewelry Creation in New York City. He produced elaborate and elegant jewelry out of golden metal, transparent quartz, glass and enamel. Later Louis was joined by his siblings Harry and Morris in the jewelry business. All facets of the business took place in NYC. “Kramer NY,” was the mark used by Louis in the 40’s and early 50’s and collectors believe this is some of Kramer’s best vintage jewelry.
