This is something remarkable and it measures just 7.5 x 5.4 x 3.1 cm.
The vug (a small cavity in a rock or vein, often filled with crystals) is of shattuckite in a blue velvety botryoidal (like a bunch of grapes) form coating the inside. As well there is a spray of acicular (needle shaped) malachite which is dark green with tiny clusters of needle shaped crystals.
There have been a number of these specimens from the Kaokoveld region of Namibia, south-west Africa but it would be hard to go beyond the beauty of this piece.
And I gave you all the meanings so you can kill the competition at Scrabulous.
