5.0 x 4.5 x 3.5 cm. This is a textbook, large grossular garnet from Lake Jaco, Mexico. The lustre is excellent, and the color is a striking, light olive-green on this sharp dodecahedron. It is actually moderately translucent, too. The contacted base reveals the distinctive, radial growth pattern with color variations. An old specimen from the 1960s or 1970s. Ex. Dennis Mullane Collection.
