The shell size varies between 9 mm and 15 mm. The shell is turbinate, narrowly but deeply umbilicated, and exhibits an iridescent blue color often obscured by whitish, thread–like lines of growth and spiral line. The shell typically has between 5 and 5½ whorls, with the first few whorls being yellowish. The shell's outer surface displays more conspicuous lines of growth between the ridges, giving it a distinctive texture and appearance. {{Cite web |title=Register of Antarctic Marine Species (RAMS) - Antimargarita dulcis (E.
