This is a beautiful 18k solid gold ring with a natural ruby. It has a single row of gold balls around the setting and the band has a line of fine twisted wire down the center.
The ruby in this ring has pinkinsh-red color and is cabochon-cut into a high-domed rectangle giving it a rich look and feel. This material comes from the Winza mine in Tanzania and is completely natural (un-heated). There are a few flaws/inclusions (veils) in this stone but it is glassy and has beautiful color for a natural stone.
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.
