The history of Theda jewelry trademark began one hundred years ago in Providence, Rhode Island. The trademark was owned by Ideal Jewelry Mfg. Co., incorporated in 1921 and located at 21 Eddy Street, Providence, RI.
The company’s craftsmen used sterling silver, marcasite, rhodium plating, 12 K gold, cultured pearl, amethyst, jade, topaz and rhinestones. Traditionally, they worked in etching technique, hand engraving floral patterns on silver. Ideal Mfg. Co signed their pieces “Theda sterling”.
Noteworthy, the company went through several renewals and changes of owners and addresses. Thus, renewed in 1963 Theda trademark ceased to exist in the 1980s. Also, reregistered in 1988 in Cranston, RI, Theda became inactive in 1995.
