Known as Lacerta viridis. Eyed lizards (or you call them jeweled lacertas) would not be showing much green at 8 inches long, and they're bite is something that you would know about! They get to around 2 feet long, although they're SVL is around the 8 inch mark if you meant that. Eyed lizards also show large, bright blue spots down they're side.
Hope this helps, and good luck! They're both pretty easy to keep and require the same conditions.
