This is an 18k solid gold ring with a pale sea foam blue-green aquamarine. The design is simple but pretty with a single row of tiny gold balls around the circumference of the band.
The stone in this ring is an aquamarine with a light blue-green hue. It has a few inclusions (mostly thin veils) beneath the surface but is still bright and glassy. It is difficult to see the color of this gemstone because the lights used to photograph the piece are passing thru the stone and reflecting off the back of the setting. It is a pale stone but it has a little more color than I can capture in a photograph.
The ring at its widest point is a little over 1/4” wide (at the front) and the band is approx. 1/8” wide at the back.
