Emma mattresses - correct model?

Hi, just bought an Emma mattress online and not sure if they've sent the correct one (no paperwork, no label!).
Meant to be a premium hybrid, but the one slogan over the cover names diamond. I gather they have made a diamond hybrid for some markets. Does anyone know if they are one and the same (can't find anything to clarify on the website).
(I've contacted them directly, waiting on reply). Thanks
