The name Grandite was created by combining the "gr" from grossular and the "and" from andradite; two varieties of Garnet. Grandite is a synonym for the Andradite-Grossular Series which is a series between Andradite and Grossular varieties of Garnet. Originally Grandite was a species name for an intermediate compositional range between Grossular and Andradite; but since the adoption of the 50% rule (dominant-constituent rule) it has come to be a generic name for the series used when the exact percentages of aluminum (Al) and iron (Fe) aren't known, and so the exact species can't be determined.
