This slab of Youngite has nice tan patterning against a translucent white background. The slab has several vugs which are quite common in youngite.

It is about 7mm thick.

Photographed wet to show details and dry to show the slab dimensions(second photo).  The dry photo is on a 10mm or 1cm to the square scale.

Both sides of the slab are shown wet so you can see the locations of the vugs. The dark area on the second wet picture is ink from a Sharpie marker.
