These stones are not the classic green of Russian Chrome Diopside (RCD), having a tiny bit of a yellowish tint, which is characteristic, I think I remember in my reading about RCD, of African Chrome Diopside. I would call the saturation of the stones in my ring "grass green." I like the stones. They are pretty, but the setting is very lightweight. But I am also a huge RCD fan so I am probably biased since I like all Chrome Diopside better than other green stones except for Demantoid Garnet. Remember ladies, RCD is UNTREATED, unlike Emerald (and most other major gemstones, except for the Garnets). I think Chrome Diopside is very much underrated as a gemstone and will probably soon gain in popularity AND price quite a bit...
