GROSSULAR GARNETS (miniature)
$148.50 AUD
Grossular is a calcium-aluminium member of the garnet mineral group, characterized by the chemical formula Ca3Al2(SiO4)3. In its composition, calcium can be partially substituted by ferrous iron, while aluminium may be replaced by ferric iron. The name grossular is derived from the gooseberry, grossularia, reflecting the green variety of this garnet found in Siberia. It also appears in other colors, including cinnamon brown, red, and yellow, and is recognized as a gemstone.
In geological contexts, grossular has frequently been referred to as grossularite. However, since 1971, the International Mineralogical Association has advised against the use of the term grossularite for this mineral.
