An early 20th c. silver filigree ring of Chinese provenance, I believe, this piece is impressive and rather colorful with its bezel set gems. The large faceted stone at the center tests in the sapphire/topaz area on my Presidium gem tester - I cannot say whether natural or synthetic yet the color is gorgeous. There are also amethysts and tiger's eye cabs . Currently a comfortable size 6, the ring can easily be re-sized. Its face is 1 1/4" tall by 7/8" wide and it weighs 9.7 grams. Not signed or hallmarked for metal content, it does test as silver and is in excellent vintage condition.
