We tried to photograph this old Mexican specimen twice to capture the luster, but to no avail. Suffice it to say that it IS QUITE lustrous, in addition to its many other merits; the most obvious being its prodigious size! But more than that, the crystal is complete all the way around (matrix contact only on the very back, giving it a fine display face). And, it has wonderful salmon-pink color and SHARP faces. Just a REMARKABLE crystal specimen of a size that really is amazing considering it has survived intact. 7 x 5 x 4.5 cm
