Understanding perfume
What does amber smell like in perfume
Amber in perfume commonly describes a warm, resinous, sometimes sweet impression built as an accord. It is not a promise that a fragrance contains fossilized amber, and it is distinct from ambergris.
A HUME Fragrance buying guide

Recognize the warm impression
Amber descriptions often suggest a rounded, balsamic character. The sweetness and texture vary with the composition, so amber is a direction rather than one exact smell.
Do not confuse related names
Amber, ambergris and modern amberwood descriptions are not interchangeable ingredient declarations. Read the seller's specific explanation before assuming the same effect or source.
Test the balance
Woods, flowers or spices may change how an amber impression feels. Compare a candidate later in the wear, especially if warmth or sweetness is a deal-breaker for you.
Try this before you buy
Record whether a sample's warmth feels sweet, resinous, woody or a mixture instead of writing only amber.
