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”.
