What does grossularite mean?
Grossularite is a mineral name for a calcium-aluminium variety of the garnet group, chemically corresponding to Ca₃Al₂(SiO₄)₃. It occurs in colours ranging from colourless and pale pink to brown, cinnamon and green, and well-formed crystals can be cut as gemstones. Mineralogists commonly use “grossular” or “grossular garnet” as related names, while “gooseberry garnet” reflects an older comparison between some crystals and gooseberries. Green grossularite is associated with the gem trade name tsavorite, although not every grossularite specimen is green. The word is chiefly encountered in geology, mineral collecting, jewellery and gemmology rather than everyday speech. Its pronunciation and double-s spelling can be unfamiliar, but its scientific name reflects a long history of mineralogical classification and provides a useful example of the many natural-history terms preserved in modern English.
nounA mineral of the garnet group, essentially a calcium-aluminium silicate, occurring in colours ranging from colourless and pink to brown and green. Its well-formed crystals may be used as gemstones.
- A calcium-aluminium mineral belonging to the garnet group, occurring in several colours and sometimes yielding gem-quality crystals.
"The necklace featured polished grossularite cabochons in a translucent honey colour."
"The museum acquired a cabinet specimen of green grossularite from a mine in East Africa."
"Collectors value transparent grossularite for its unusually attractive green colour."
The plural is used when referring to multiple mineral specimens or occurrences of the mineral.
"The museum's display includes two rare green grossularites."
Some grossularite crystals look so uncannily like tiny gooseberries that the mineral inherited their name.

Etymology of grossularite
Grossularite was formed by alteration of grossular, the earlier name for the mineral. Its name comes through New Latin grossularia from Medieval Latin grossularia, ultimately from Latin grossularia, “gooseberry”; the mineral was named because some of its crystals resemble gooseberries.
How grossularite is actually used
This is primarily a specialist mineralogical and gemmological term, used in geology, mineral collecting and jewellery. It should not be treated as a general name for all garnets.
Easily confused with grossularite
Grossular is the older related mineral name and is still used for the variety, whereas grossularite is the principal modern mineral name.
