Dirty and earthy are two words that mean about the same to me in fragrances. Earthy being the smell of soil, trees, plants in their natural form, which tend to smell dirty. Have you ever smelled amber?
Have I smelled Amber meaning "ambergris," or meaning the fossilized pine resin? Or are you talking about liquid amber resin, known as styrax? Amber as a genre is actually very interpretive... any "pure amber essential oil" you find will almost always be a composition of ingredients, since making amber absolute for perfume purposes from fossilized resin doesn't occur (except perhaps in some remote location that I'm unaware of); if you find anyone selling it as such, chances are that it is nigh on impossible it is anything but a fake. That's why there really is no such thing as "true amber" perfume. If you are talking ambergris, then we have a completely different creature entirely. Hence my original question to you.
Every fragrance house, especially niche ones, seems to have an amber. From my experience, much of what is called "amber" is sweet and resinous and built off of labdanum. I have actually smelled amber resin (the fossilized kind) burning and it smells very beautiful - very resinous. As far as pure amber resinoid or absolute? I'm not convinced that anything I have ever smelled that claimed to be such was authentic (and I have smelled a LOT of them). What is your reference for what the note "amber" is supposed to smell like?
