An excellent deal of 4 water-clear, colorless, totally gemmy thumbnail topaz crystals with simple chisel terminations to complex pinacoid terminations from Vietnam. Some prism faces are lightly striated, while others are glass-smooth. Trivial edge damage to two of the crystals, but nothing extraordinary at all. 2.4 x 1.5 x 1.2 cm (tallest)
