This is a 22k solid gold ring with a deep red ruby. The design is based on an ancient Etruscan style with intricate twisted wire details.
The ruby comes from the Winza mine in Tanzania and is completely natural (unheated). It has deep red color but is still bright even in subdued light and has good clarity. There are a few minor imperfections such as ‘veils’ below the surface which is common for natural untreated ruby.
The ring at its widest point is approx. 3/8” wide (at the front) and the band is approx. 1/8” wide at the back.
