Most of the garnet at the Tuticorin beach in south India is 80 mesh, and ranges from 56 mesh to 100 mesh size. [citation needed] River garnet is particularly abundant in Australia. The river sand garnet occurs as a placer deposit. [70] Rock garnet is perhaps the garnet type used for the longest period of time. This type of garnet is produced in ...
Rhodolite is a varietal name for rose-pink to red mineral pyrope, a species in the garnet group. It was first described from Cowee Valley, Macon County, North Carolina. [2] The name is derived from the Greek "rhodon" for "rose-like", in common with other pink mineral types (such as rhodochrosite, rhodonite).

The name is a corruption of alabandicus, which is the name applied by Pliny the Elder to a stone found or worked at Alabanda, a town in Caria in Asia Minor. Almandine is an iron alumina garnet, of deep red color, inclining to ...
Thin section (crossed polars) of Garnet-Mica-Schist showing a rotated porphyroblast of garnet, mica fish and elongated minerals. This specimen was from close to a shear zone in Norway (the Ose thrust), the garnet in the centre (black) is approximately 2mm in diameter. Very distinctive textures form as a consequence of ductile shear.
Colophonite, less commonly kalophonit (from Ancient Greek: κολοφωνία, kolophonia, rosin or rosin colors) — an obsolete historical name for a brownish calcium-iron mineral of the garnet family, a variety of grossular (later, andradite), discovered as an associated metamorphic mineral in the iron ore mines of the southern Norwegian islands, primarily Tromø (near Arendal).
fracture front – the line separating the rock that has been fractured from the rock that has not; fracture tip – the point at which the fracture trace terminates on the surface; fracture trace – the line representing the intersection of the fracture plane with the surface; Griffith cracks – preexisting microfractures and flaws in the rock
