Acqua di Parma Iris Nobile edp is as rich as its golden color and its purple packaging portend. The composition features orris, not iris petals, so it's important to know this, since someone looking specifically for the flowers, not the roots, of the iris plant may be disappointed. On the other hand, anyone looking specifically for orris is bound to enjoy this creation, which has big sillage and great longevity in this, the eau de parfum concentration.
Many non-iris notes are also listed for Iris Nobile, and the overall creation is thick and and viscous feeling without being very sweet. To my nose, the various notes blend together fairly seamlessly, and the composition is pretty linear. The woody quality contributes a great deal to its unisex demeanor, but I suspect that some fellows still might find this perfume a touch too feminine.
As far as other iris perfumes are concerned, Iris Nobile lies much closer to the Ormonde Jayne orris perfume and the Yves Rocher Iris Noir, although I think that the quality is much closer to the former than the latter. This is certainly a dark and substantial iris perfume, not a light and fluffy one à la Prada Infusion edt or edp.
The name correctly suggests that this perfume conveys a noble quality. It shimmers in its bottle as on this skin, and while it seems glamourous, it is not a cheap, superficial glamour. There is real depth to this creation, which is a complete and utter pleasure to wear.
