This is a 22k solid gold ring with a beautiful purple sapphire. The design is based on an ancient Etruscan style with intricate twisted wire details.
This sapphire comes from the Winza mine in Tanzania and is completely natural (unheated). It is a really nice violet-pink color that is rare for sapphire. There are a few imperfections such as ‘veils’ below the surface which is common for natural untreated sapphire.
The ring at its widest point is approx. 5/16” wide (at the front) and the band is approx. 1/8” wide at the back (see photo with older U.S. dime for size/scale).
