This is a combo piece with both Chrysocolla and Malachite growing together from a copper deposit in Chile. Both Malachite and Chyrsocolla are copper based minerals that grow in the oxidation zones of copper deposits. There's a group of copper minerals that all psuedomorph after each other, meaning one will take the place of the other. Those in order are Azurite, Malachite, Chrysocolla, and then Shattuckite. This means this piece used to be all Malachite and that just the top portion has gone through that psuedomorph into Chrysocolla. This particular piece has a longer botryoidal formation than most. It almost looks like a bunch of small stalactites, making it very unique.
The top part of the tallest "stalactite" was broken off at some point prior and glued back into place. It does not detract from the beauty of this piece, but some collectors would like to know.
This piece measures approximately 3.8cm wide x 3.1cm long x 3.4cm tall. It comes with a display card listing the main mineral (Chysocolla) and the locale.
