This piece is very fine in that it has eye-visible, large-for-species, GEMMY, crystals of sklodowsite perched on contrasting matrix of gypsum. It looks like lemon-yellow candy on sugar, to the eyes. Crystals are 2-4 mmin size, and are just literally so bright neon yellow, it is hard to see them for the glare of the color reflecting back. This is, for quality, the best example I have ever seen from the locale by an order of magnitude...usually they are just boring micros.
