Heart bangle

Aquamarine rose gold heart bangle. Magnetic clasp. Unsure of actual material but the stone is an aquamarine color and the bangle is of rose gold color. There's an area where it looks slightly darker than other areas (pictured) and some minor blemishes which I tried to photograph but it's a bit hard to show. Not very noticeable Probably worn once. Approximate measurements in photos. Please review all photos. Comes from a smoke and pet-free home.
