The Peridot offered here are from China, Pakistan, and Arizona and are a vivid Sour Apple Green. While the parcels are mixed quality, the singles have been carefully checked by 2 people. Although there may be something on the surface, the singles I am listing are expected to facet clean stones. Having said that, Peridot is a notoriously hard stone to grade in the rough. If by chance we missed something, please rest assured I stand behind everything I sell with a no questions asked return policy. The Chinese Peridot has had a particularly good reception amongst the faceting community. The stone in the photo that was cut by Jason Vogel is a Chinese Peridot.
