LAB-GROWN DIAMONDS I SWISS MADE
Made in the heart of Switzerland
Ammil stands as a Swiss producer of sustainable lab-grown diamonds. Our diamonds are crafted using local, renewable energy, ensuring minimal environmental impact.
Redefineing the Diamond Industry
Ammil is committed to eliminating opacity in the diamond industry and setting a new ethical standard. We ensure full transparency in our supply chain and focus on ethical and sustainable production practices, providing a clear, responsible, and traceable alternative to traditionally mined diamonds.
Authentic Sustainability
At Ammil, we reject greenwashing. Instead of relying on carbon credits, we built our production facility in a location with a surplus of renewable energy. This ensures that no additional energy production is required for our manufacturing needs, making our process genuinely sustainable and self-sufficient.
Why Muotathal, Switzerland?
Our diamond production facility is located in Muotathal, in the canton of Schwyz.
-
100% renewable energy: Powered by solar energy during the day and hydroelectric power from the local Muota River.
-
Swiss-sourced raw materials: We capture carbon from Swiss air to obtain methane and hydrogen, ensuring a circular and responsible production cycle.
Our Process
Ammil provides an environmentally friendly alternative, ensuring a premium and sustainable choice for the discerning consumer.
Step 1
Growth – Cultivating a Diamond from a Seed
Our process begins with a diamond seed, a microscopic sliver of pure carbon that serves as the foundation for each diamond. Using advanced Chemical Vapour Deposition (CVD) technology, the seed is placed in a highly controlled growth chamber. Inside, the chamber is filled with a carbon-rich plasma, where carbon atoms bond to the seed layer by layer, replicating the natural diamond-growing process.
​
Over several weeks, the diamond grows into what is colloquially known as a 'diamond cake'—a raw, uncut diamond block ready for transformation.
Step 2
Cutting and Polishing – Where Science Meets Craftsmanship
Once the diamond cake reaches the required size, it undergoes a meticulous cutting and polishing process:
-
Each diamond is assigned to an individual artisan—not mass-produced on a production line.
-
Our cutting and polishing experts utilise precision lasers and polishing tables to carefully shape rough material into exquisite, precision-cut diamonds.
-
We take pride in fostering inclusivity in our workforce, employing and training female artisans in an industry where they are underrepresented.
-
Our polishers earn fair wages, multiples higher than industry norms, ensuring they can support their families and take pride in their craft.
-
Senior polishers have the opportunity to become master polishers, fostering career growth and social mobility within our workforce.
