About Peruvian Quantum Cuattro

Being straightforward, originally, Quantum Cuattro 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 chrysocolla, which was found in Peru. It was originally sold as chrysocuarzo (Chrysocolla in quartz), but then Peruvian dealers switched to rebrand it as Quantum Cuattro 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 Cuattro.

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

We grade Quantum Cuatro in three quality classes:

Quantum Cuattro 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 Cuattro Mixed Grades: All coloration grades from Quantum Cuattro Quartz to Premium come without sorting.

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

Why Gemrock Quantum Cuattro Crystal Products are truly ethical:

Founded in 2017 by biologist and professional nature conservationist Stefan Austermühle, Gemrock was born to be more than just a crystal wholesale business. As a result, Nature conservation and ethical workers’ treatment throughout the entire production chain are at the core of our business. We are changing the crystal industry for the better one crystal at a time.

  • We do not source our raw materials from conflict areas, from mines that employ children, from drug production areas, or mining that finances genocide and civil war.
  • All our gemstones, silver, and gold come from legal sources. We do not support illegal mining or shadow business.
  • Our entire production (crystal carving, silver and goldsmithing, as well as jewelry production is in-house. We control 100% of the production chain.
  • Gemrock employees are paid fair salaries higher than the industry average. They are hired under legal labor contracts with all legally required labor benefits. Excellent work is motivated with bonuses and our employees get a share of the company’s annual profits.
  • Hiring is independent of any non-work related factors (gender, skin color, nationality, or else). Only knowledge and labor quality do matter.
  • We offer our employees safe labor conditions.
  • Saving water and energy, and re-using and recycling materials to the maximum is an ongoing effort.
  • We constantly measure our carbon footprint and neutralize our climate impact by financing a tree-planting project.

The maximum possible transparency is Gemrocks’ most important communication rule. You can find ample information about our ethical business in our blog (on this website) and on all of our social networks. For more details on our ethical standards, read here:
