I adore this peridot heart. It's set in sterling silver, and the chain is a silver Asprey chain that belonged to my mother. The cut of the heart is named a convex cut. I bought the pendant because I liked its color, but I have no idea if this is considered a high-quality hue or not. I'd be interested in the opinion of color experts! I love the way that peridot is completely un-enhanced. The paler photos where it looks more yellow are in daylight, but it looks much more deep grass-green in real life like the first photo. Enjoy! xxx
