History

Stuart company, and was named after a Stuart granddaughter. It sold jewelry through home jewelry parties and bought designs from freelancers and outside firms rather than relying on an in-house designer. It was among the largest direct-selling jewelry companies in the 1960s and 1970s. The parent company went bankrupt in the early 1980s, home parties ended in 1984, and later revivals had failed by 2009.

  • SaC stands for Sarah Coventry, not a separate name.

Where sources disagree: Founder named differently: Charles H. Stuart (RCJ, Collectors Weekly), Lyman K. Stuart (Wikipedia), Bill Stuart, grandson of C.H. Stuart (Life in the Finger Lakes). Bankruptcy: March 1981 (RCJ, Wikipedia) vs 1984 for the C.H. Stuart parent (Finger Lakes). Signing start: RCJ has SC after 1953, Wikipedia says unsigned through 1955. Sources don't say how the marks were applied.
