Hi Rock man456,

The locality seems correct but for malachite, if there is no realy distinct matrix, it's difficult to say.
On the other hand, the dark green crystals are malachite and not dioptaas, a frequent mislabeling.

With the quantity of malachite coming out of Shaba for the moment, I'de say between $40 and 60.

I hope this helps.

Take care and best regards.

Malachite on malachite, pretty piece, but you can choose from tables full at any decent show; maybe $75 max, as it is a nice piece, no damage.
