Summary: I don't feel my nose is incorrect in thinking that the original Canali, Canali Summer Night and Canali Black Diamond smell pretty much the same. The bottles are seemingly the only difference. The only cologne offering that smells different by Canali is Canali Style. This one doesn't smell bad, but having owned the original Canali, and currently the Summer Night one, I don't notice too much variation, regardless of what the notes listed are.
Summary: I really like this one. Has a lot going on. There are lots of notes you can pick out if you try, but my main impression is: sweet, floral, fruity, bright, and yet still somewhat masculine in character. Perhaps it's the leather and/or woods that keep it from tipping into feminine territory. Unlike the other Canali scents I have tried, this one has good projection and longevity.
Summary: An unluckily discontinued blend of fruits ( we must underline the notable strong orangy-neroli accord and the peaches) greens, sweet spices, nocturnal flowers, woods and synthetic suede in the way the outcome is a delicious silky orangy-leathery fragrance with nuances of melon, peaches and jasmine.
Summary: Way too many notes to break apart what specifically is noticeable. But, I can confidentially say that the opening is reminiscent of Polo Sport, then as it dries a little, it becomes less boring and a little more distinguished with its noticeable leather note/accord along with the violet. These are which stand out the most to me, but as others have said it's blended together very smoothly so that you can't so much break it into individual notes.
Summary: Black Diamond is not a "kitchen sink" as stated in some of the reviews. Instead, it is a charismatic cocktail of notes usually associated with a modern "black" frag. The difference here is, that it does not go overboard or push all the sweet, fruity and predictable to the surface. I usually dislike apple, melon, violet, pineapple and peach in a modern frag. They are severely overused nowadays.
Summary: I'd have to agree with Mario_Justiniani. Its name really doesn't describe what it smells like. "Acqua of Assorted Melons with Subdued Spices" really does sound about right. It's a foody perfume to me. Lemon & spices in the opening (the lemon smell being the bergamot, I guess). Drydown is very foody. It's not particularly soapy. Spices and fruit. Maybe a leathery-like smell. I'd compare it to Carven Homme, except I gave my sample away.
Summary: I find nothing about this scent to get excited about and I find nothing about this scent that is nausiating. It is middle of the road with everything thrown in. The opening is powerful and confusing. The middle is nice with violet and wood, but nothing really special. The bottom is woodsy/musky, but not the best of that genre. I have to say, "no" to being part of my collection but I can not say do not buy it, you might like it.
Summary: This is a tough one. I just don't like what I perceive as a wall of notes thrown in my face from the very beginning. It's certainly not artful, if one cares about that facet of perfumery. On the other hand, it is pleasant, no doubt, at least on a basic level. So, I think I like this enough to keep it in my rotation, but I don't think I'll ever consider it "special" in any way.
