As soon as you open the box you get that highly recognisable scent that you get from the original Diamonds. At first you think it's the same but once I sprayed on my wrists I could easily tell the difference. Although EXTREMELY similar to the original it's slightly more intense and stronger than before. There is also the slightest hint of a fruity twine to the scent, enough to make it an improvement but not enough to take away from the distinctive trademark scent of Armani Diamonds.
I put one spritz on myself in the afternoon and the scent still remained intact until the evening time, definitely an improvement on the original. The reason why I prefer this version is because it has a long lasting smell which the original didn't have, although there was an intense version of Diamonds released a few years back I never took to it because the scent was TOO intense. Black carat has a nice balance between both.
If I could compare Diamonds, with Black Carat I would say that the original is elegant and Black Carat is sexy. Even the bottle is sexy! Shiny Diamond cut black glass. I can safely say that I will not look forward to this running out.
I got this bottle free so I wasn't sure of the price, I checked out for you that the popular stores like boots and House of Frasier are selling Black Carat 50ml for £49. But fragrancedirect.co.uk is selling the 50ml bottle for £41, that was the cheapest I found online.
