I got this 3.5 ct. Emerald almost 10 years ago at a jewelry auction. It's natural and has an oval cut. I tried my best to represent it in the photos, it's tough to photograph an oval gem! It's rather large and isn't on the higher end as far as grade (otherwise I'd sell it for thousands!). It's a deep green and would make an excellent accent piece on jewelry. It's 100% guaranteed natural and authentic. This is a great loose stone for a good price! I'm selling a ton of stuff since my apartment in New York is tiny. Enjoy!
