Sonora Sunrise/Sunset Chrysocolla Cabochon
Sonora Sunrise/Sunset Chrysocolla Cabochon
This material comes from the northwestern region of Sonora, Mexico and is known for its amazing color play of blue-green chrysocolla and red cuprite, which in some specimens is also contrasted with fantastic inclusions of black tenorite. This trapezoidal freeform cab is showing a slightly speckled midsection of cuprite sandwiched between two belts of chrysocolla dappled with bits of darker green and black, while the back of the cab is showing chrysocolla and a few dabs of black tenorite only. Though Sonoran Sunset Chrysocolla is soft and may benefit from stabilization, this cab is untreated. My experience with this stone is that it cuts quite smoothly; it's dense with a heavy feel in hand and takes a beautiful polish readily - a gorgeous material well deserving of its popularity.
