Note: David Spada (December 5, 1961 - May 13, 1996) was a jewelry designer in New York City in the 1980s and 1990s and the creator and marketer of Freedom Rings
Spada attended the Parsons School of Design in the early 1980s, graduating around 1982. 
He began making jewelry as a student, and his work gained recognition as early as 1984 when a piece made from orange rubber tubing was featured in the New York Times.
Spada became known for his creations in colored anodized aluminum, creating a wide range of shapes from the material, ranging from rings and earrings to clothing and swimwear embellished with aluminum decor.
He eventually opened a boutique, Casa di Spada, in New York's Lower East Side, which sold his jewelry designs, clothing, and custom items.
According to a NY Times article from 1992, the freedom rings were introduced in 1991 in San Francisco as a fundraising item at the gay and lesbian Community's annual Freedom Day Parade and quickly became a national trend. The colored aluminum rings come in colors of the rainbow, based on the gay pride flag, and have evolved as a symbol of Gay Pride.
"Colors symbolize happiness and represent the diversity of the community," David Spada.
Spada died of AIDS complications on May 13, 1996.
