A stunning champaign colored Topaz crystal, measuring 4.2 x 3.5 x 3 cm, perched on Albite with Muscovite. There is a line around the middle of the crystal, which is either a natural internal fracture or a repair. A repair would not be unusual for gem crystals, but I was not able to feel a seam with my finger, which would be more consistent with a natural internal fracture (not a complete break, per se). Either way it is in great condition and well worth the price.
