If you love onyx...or just black in general, this is a really unique ring for you.
Architectural stepped shanks that have been layered on top of one another to create dimension and texture to the band. Ovular stone is set in a saw tooth bezel and has no cracks or chips.
No hallmark is present, but looks like it has been sized down based on back of band. Has a southwest flare, but could possibly be a piece from Mexico. Lovely either way!
Size 3.75-4 US
Band Width approx .25"
Shank Width approx 2.25" at widest spot
Rectangle Face Height .75"
Onyx is .25" x .75"
Note: I do not polish any of my pieces pre or post purchase. I believe it takes away the beauty of its past lives and vintage appeal.
