On this matrix specimen, the highlight for me is the shocking stark color contrast between the crust of yellow mimetite and the tabular, lustrous, translucent, orange, wulfenite crystals (to .8 cm across). My guess as to the age of this specimen is that it probably predates WWII, judging from the accompanying label. You see very few large Tiger pieces on the market today, and frankly most Tiger wulfenites you do see just aren't that pretty overall, though they may have larger wulfs occasionally upon them in vugs and crannies. This is a beautiful, rare old piece of large size and color splash!
