Absolutely gorgeous, sparkling, glassy and gemmy, crystals of butterscotch-colored wulfenite, to .5 cm across, completely drape this 3-dimensional matrix specimen. Although the crystals are small there are a lot of them, and they are highly reflective. The overall effect is that of city lights at night, from the air. It is MUCH better in person, and one of the most sparkly of the lot.
