Why Gemrock 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:
