This specimen features two doublet clusters of doubly-terminated willemites, each about 4 cm, flanking a large section of massive calcite matrix. Actually, you can see there are other willemites embedded within. The contrast, when shot with ultraviolet light, is stark and dramatic as you can see. This is an old specimen, from the stock of Arthur Montgomery (1909-1999), well known field collector and dealer. His label dates it to (1937-1941). Until recently in the George Elling Frankli Collection
