vermeil

Vermeil comes from Old French vermeil, from Latin vermiculus (little worm), diminutive of vermis (worm). The worm in question was the kermes insect (Kermes vermilio), crushed to produce a red dye. Vermeil originally meant the red color produced by this dye. The jump from 'red worm dye' to 'gold-plated silver' happened through a specific technique: medieval goldsmiths used a mixture of gold, mercury, and red-tinted substances to create a warm-toned gold coating on silver. The reddish warmth of the finish gave it its name.

The Vermeil Rooms in the White House — the set of rooms on the ground floor used for receptions — take their name from the vermeil collection displayed there. Over 1,500 pieces of vermeil tableware and decorative objects, donated by Margaret Thompson Biddle in 1956, give the rooms their identity and their name. The word vermeil, in American English, is most associated with the White House.

In French, vermeil still means 'bright red' or 'ruddy' — a word for the color of healthy cheeks or autumn apples. The metalwork meaning is secondary in French and primary in English. The same word occupies different semantic territory in its two main languages.

Olympic medals provide the word's most specific modern definition. According to the International Olympic Committee charter, a gold medal must be at least 92.5% silver coated with at least 6 grams of gold. This is, technically, vermeil. Every Olympic gold medal since 1912 has been a vermeil medal. The word for a worm-dyed red color now names the most prestigious award in international sport.
