Being straight forward: Originally Quantum Cuatro was the trade name for a mineral combination of shattuckite, dioptase, malachite, and chrysocolla on smoky quartz that was found in Namibia. Peruvian Quantum Cuatro is a very similar combination of quartz, malachite and crysocolla, that was found in Peru. It was originally sold as chrysocuarzo (Chrysocolla in quartz) but then Peruvian dealers switched to rebrand it as Quantum Cuatro when the nearly identical look and very similar composition became obvious. We are trying to make people aware of this difference by clearly stating that our products are made from Peruvian quantum cuatro.

Peruvian Quantum Cuatro is sourced from Tentadora mine in Peru. It is a a huge single body of quartz. Malachite and chrysocolla have infiltrated finest haircracks and spaces within this mass of quartz and have filled cracks and holes in the quartz mass with a thin overlay of their botroidal microcrystals. The quartz mass also exposes regularly big pockets of quartz crystals that are overlayed with dark copper oxide, as well as malachite and crysocolla crystals. Those crystal clusters are known as Tentadora mine crystal clusters. Apart of our products made from the Quantum Cuatro quartz mass we do sell those clusters in flats for commercial clients.

We do grade Quantum Cuatro in three quality classes:

Quantum Cuatro premium (or TOP): Material with very strong coloration with a high content of malachite and chrysocolla, often with dark copper oxide and many times with crystal filled cracks.

Quantum Cuatro Mixed Grades: All coloration grades from Quantum Cuatro Quartz to Premium as it comes without sorting.

Quantum Cuatro Quartz: mainly transparent and translucent milky quartz with a touch of green and tourquoise color from small quantities of chrysocolla and malachite, comes with cracks that show botroidal microcrystals.
