A Wonderful and Rare Antique Art Nouveau Era - Arts & Crafts Blue Snowflake Agate Ring Vintage c.1890. This beautiful antique ring holds a lovely grey-blue snowflake agate at its center measuring about 12 x 14mm oval. The setting is beautifully detailed in natural Art Nouveau - Arts and Crafts movement botanical motifs. Both the Art Nouveau and Arts and Crafts movements were around 1890 and took from nature for their inspiration. These pieces were only made for a very short duration, thus making them hard to find today. The stone has been secured with jeweler's resin in the back at some point over the years. The setting is composed of sterling silver with a lovely soft patina. Overall the ring measures about 9/16 inch long by about 11/16 inch wide from side to side. Ring Size: about 5 (could be resized by your jeweler or ask me about using mine before shipping). This ring was acquired through an estate collection and is in lovely vintage condition.
