The Heights Mine is acclaimed for its quality green Fluorites, and this is no exception. The interpenetrating twins, a classic form for English Fluorites, are gemmy and attractive, with the unusually elongated twin being 2 cm long. The more equant Fluorites have sharp and colorful purple cores which are more dominant than the phantoms you commonly see in England. This is a fine, choice miniature with excellent fluorescence. Collected by Lindsay Greenbank in 1993 and nicely trimmed to a superb miniature.
