An elongated plate of cream to pale creamy-tan Willemite made-up entirely of crystals of between 2 and 5 mm. The crystals are glassy with a bright pearly lustre and on the underside are scattered sub-mm golden-tan crystals of possible Arsendescloizite. Under LWUV the Willemite fluoresces a medium yet strong mustard-yellow and in SWUV, snowy-white. An excellent Willemite and for Tsumeb, an unusual colour.
