noun
eardrop; drop earring
Refers to an earring with a dangling pendant, as opposed to a simple stud. Common in fashion contexts.

She wore eardrops to the party.
イヤリング is a broader term for any earring, often clip-on or non-pierced types, whereas イヤドロップ emphasizes the pendant design.
Borrowed from English 'eardrop', referring to a drop-shaped earring or an earring with a pendant.
