Just a little plastic costume jewellery information featuring the Squares bracelets produced by Coro. The US jewellery company Coro jewelry which closed in the 1970s; produced the vintage bracelets which had square plastic inserts in about 70 different colors. From about the middle of the 1950s to the early 1960s for about 6 years, they released different colors for fall (darker) and spring (pastel). This information is in the "Mid Century Plastic Jewelry" by Susan Maxine Klein.
This Squares yellow-cream vintage bracelet is now available but instead of being signed by Coro - it has the Jewelcraft signature. It was probably made here in the UK for the English market, although some Jewelcraft jewellery was also made in the US. They are just so suitable to collect as well as to wear.
