What does grossular mean?
Grossular is a specialist noun in gemology and mineralogy for a variety of garnet, most often recognized in red and green forms. It can stand alone when discussing stones, cut gems, or jewellery, and it is also commonly used attributively in the fixed phrase “grossular garnet.” Green grossular may be marketed as tsavorite, a vivid green material prized for jewellery, while reddish grossular is often associated with the trade name cinnamon garnet. In everyday English, the word is uncommon and appears mainly in catalogues, mineral descriptions, lapidary writing, and gemstone reports rather than general conversation. Modern mineralogical terminology often distinguishes grossularite, the formal name of the relevant garnet mineral, from the broader or more traditional variety name grossular. Recognising the word is useful because “garnet” covers a large family of minerals, and grossular identifies particular colours and varieties within that group. In American English, its pronunciation is most commonly represented as GROSS-uh-ler.
nounA red or green variety of garnet, especially one valued as a gemstone. The green variety includes the vividly colored stone known as tsavorite.

"The jeweler set a vivid green grossular in a gold ring."
"The jeweler set a vivid green grossular in a gold ring."

The plural is rare; discussion more often uses the word attributively or refers to the relevant material simply as garnet.
"Two rough grossulars were displayed under strong lighting."
Despite its grand-sounding name, grossular traces to the Latin grossulus, a diminutive meaning “rather coarse.”
