This specimen is an elegant, large crystal of the rare species hambergite. It actually splays out and broadens towards the top, ending with a fat, superb termination. The lower back edge may seem jagged at first glance, but is all terminated; and in person this looks like a curve and draws the eye up to the termination, making the piece look more elegant than blocky. This is a freak crystal, certainly among the larger examples of its species. The steeply pointed termination here is distinct from most Pakistani, California, or Madagascan hambergite I have seen (and those all of smaller sizes). Hambergite is fairly light in weight. This has a mass of 225 grams, a lot less than you would expect for the size. This specimen came out of a major private collection in Russia in the 1990s, and has since been in another major private collection. Information given on sale. Joe Budd Photos.
