On a bridge-shaped matrix, a "cluster of clusters" of cavansite stretching 9 cm across! The cavansites are speckled with little stilbites down to micro size for an unusual accent. OVERALL A HUGE AMOUNT OF COLOR; an incredibly rich specimen! This plate has nearly zero damage - it really is as close to pristine as you can ask. From the Indian collection of collector George Feist, known very widely for his superb Midwest collections. This one is a super old-timer now, from the mid-90s I'd guess.
