The blue/green is Chrysocolla,
the red is Cuprite,
(but it also has Chalcotricite, which is the orangey red),
and the black is Iron.
It is known as Sonora Sunset or Sonora Sunrise.
The mostly solid red cabochons are sometimes called Crimson Cuprite.
This lovely cabochon material is from the Millpillas Mine in Sonora Mexico.
The mine opened in 2006. Though most copper mines are open pit mines, this material is covered by 1000 feet of gravel!
