This is a fine, near pristine, aesthetic cluster of three glassy and gemmy, colorless topaz crystals. The largest is an equant crystal measuring 5.5 cm in every direction. Near the base of the large crystal are four parallel (internal) lines exhibiting the perfect basal cleavage of topaz - interesting contrast to the geometry of the outside crystal. The piece is complete all around and has a sparkly, glassy appearance to it that is very attractive. This is an excellent example of a quality specimen from the heyday of Brazilian minerals. 386 grams. Obtained in 1995 from a major Brazilian dealer, but it probably dates back to the 70s or before, by style.
