Item Description
The Tip Top pegmatite is renowned for its rare phosphate species and this showy and rich plate includes at least three of them the quartz matrix wedge. Small vugs host numerous sparkly very dark brown to black robertsite microcrystals; olive-green crusts of leucophosphite are scattered about; and rose-red glassy hureaulite crystal clusters are noted. It is rare to see these three rare phosphates in association on the same rich specimen from this locale.
