A superb, sharp copper tetrahexahedron crystal (2.3cm) is perched aesthetically on "legs" of smaller copper crystals. The excellent patina is lustrous and colored like fine milk chocolate, considered very desirable because it shows no signs of chemical cleaning or brightening. As well, dramatic matrix-bound crystals like this are uncommon and the tetrahexahedron has added value. 4.7 x 3.7 x 2.3 cm
