With the onset of Black Tuesday in 1929, the demand for fine jewelry virtually disappeared. To both stay in the business they loved and avoid being saddled with the debt of Depression-battered customers, the Ciners became the first and only American fine jewelers to make the switch to manufacturing high-quality costume jewelry. Recognizing the need for quality costume jewelry with the same appeal as fine jewelry allowed Ciner to survive the Great Depression.
In 1930, the Ciners created their own line of fine costume jewelry, first in silver, then in white metal. With its success, the family business was rapidly becoming specialists in high-quality costume jewelry, working to master and to develop a special kind of rubber needed to make molds that could stand up to heated, liquid metals. Throughout the 1930’s, Emanuel, Irwin, and Charles Ciner were responsible for a variety of technical innovations in costume jewelry including perfecting the use of white metal, a strong but workable blend of tin and other metals. They also contributed to the development of induction casting, and helped develop a special kind of vulcanized rubber that could withstand heated molten metals.
"The CINER name at once signified the very finest in quality jewelry of this relatively new genre, a distinction that remains to this day"
Like any resourceful American entrepreneur; Irwin enlisted the help of the family dentist, a specialist in molding perfectly smooth inlays, to help develop a higher-quality jewelry molding method than existed at the time.

During WWII, consumer use of metal was severely restricted. This almost bankrupted CINER- until the family offered its unique molding technologies to the US military. Used for munitions and other applications, these war time efforts kept the Ciners in business
“In 1946, Ciner starts advertising in national magazines such as VOGUE and Glamour with the slogan, “Look for the Sign of Ciner”
In 1979, Irwin’s daughter (and Emanuel’s granddaughter), Pat Ciner Hill, assumes control of Ciner together with her husband, David Hill. Pat comes on board during an economic downturn, just as her father did during his first decade in the business with the Great Depression. Instinctively, she senses that costume jewelry was about to have a moment, “Like it always does when times are tough economically.”
David Hill, who brought his love of costume jewelry, appreciation of fine designs, and mechanical knowledge, successfully led the family business with Pat for the next several decades until his passing in 2008. In 1984, Jean Hill becomes the fourth generation of Ciner to join the family business, leading the company with her parents, and continuing the legacy of producing and manufacturing high quality costume jewelry in NYC.
The Hills prepared through diversification, complementing their archive of superlative, conservative classics with animal head pins, bold cuff bracelets, semi-precious beads, pearls, and crystals, and younger and slightly less formal looks.
In 1992, Ciner celebrates its 100th Anniversary- a milestone recognized by the New York Times, Women’s Wear Daily, fashion magazines and by many admirers of the Ciner tradition. Ciner starts designing and selling private label collections to retailers and designers worldwide
Ciner is featured in W Magazine’s iconic July issue with Angelina Jolie and Brad Pitt shot by Steven Kline. In this famous story “Domestic Bliss”, Angelina wears Ciner earrings in several of the photographs.
2015 saw the launch of Ciner’s first website.
