- noun a deep red garnet consisting of iron aluminum silicate
Sorry, no etymologies found.
These had a composition between almandite and pyrope, that is, they had both magnesium and iron with aluminum and silica.
These are all silicates, the almandite garnets being silicates of iron and aluminum; the pyrope garnets are silicates of magnesium and aluminum; the hessonite garnets, silicates of calcium and aluminum, and the andradite garnets, silicates of calcium and iron.
Brazil, from its prolific gem gravels at Minas Novas, supplies good almandite, and smaller quantities are found in many different localities.
Pyrope and almandite garnet tend to merge in composition and in properties, and the beautiful "_Rhodolite_" garnets of Macon County, North Carolina, are between the two varieties in composition, in color, and in other properties.
As many such garnets belong to the mineral species _almandite garnet_, there is little objection to the continuance of this practice.
The so-called almandine garnets of the jeweler are frequently of the almandite class and tend to purplish red.
