Best to qualify the "type" of amber that you're looking for. There are so many variations on amber, you could build a diverse collection centered just on that note. Do you like gourmand or dry? Heavy, or light? Leathery or floral? Many will align with some of these characteristics (to name just a few).
For instance, Annick Goutal Ambre Fetiche is a thick and heavy semi-sweet amber, slightly smoky and leathery. Really nicely done for that type. OTOH, there's Etro Ambra, which is a lighter, slightly drier amber. Maitre Parfumeur et Gantier Ambre Precieux is rather gourmand, as people have described. If it's too sweet, they have a limited edition Ambre Precieux Ultime, which is darker and drier.
Anyone tried "L’Artisan Parfumeur L’Eau d’Ambre Extreme Eau de Parfum"? If yes, then please share the feedback.
How we can compare it with "Ambre Preciaux"?
