Eco Synthetic Diamonds

Gemstones for eternity

Diamonds are older than the history of mankind, formed deep beneath the earth's surface under enormous pressure and incredible heat. And as soon as people discovered them, they were spellbound by their fascinating beauty. As if a magic emanated from them, in ancient Greece they were considered tears of the gods, sparkling witnesses of infinity. But as beautiful and enchanting as gemstones are, in many cases their origin is uncertain.

How are synthetic diamonds made?

Natural diamonds are born in a fiery heat. The same is true of stones grown in the laboratory in their likeness - including diamonds produced using the so-called CVD process. That stands for chemical vapor deposition. To do this, a plasma of unprecedented energy density must be generated. In a laboratory south of San Francisco, our partners Diamond Foundry are building novel plasma reactors with hundreds of individual precision-engineered parts.

Diamonds can be created in a plasma as hot as a small sun on Earth. In this heat, atoms can attach to and enlarge the natural diamond crystal lattice of the diamond that serves as the foundation for the lab-grown diamonds in this process. One by one, the atoms stack on a thin foundation of diamond, expanding the unique crystal structure of the seed diamond. Atom by atom, it grows into a pure, jewel-sized rough diamond.

High Pressure, High Temperature

Our partners Swiss Diamond Vision work with the HPHT process to produce lab-grown synthetic Eco Diamonds. HPHT stands for High Pressure, High Temperature. In this process, which mimics the natural formation process of diamonds, 2H hexagonal graphite is placed in growth cells and fed into so-called cubic presses where the graphite is subjected to 60-70,000 bar. Graphite is a natural manifestation of the chemical element carbon, which has a hexagonal crystal structure on the outside. The interior of the growth cell is first loaded with catalysts and seed diamonds and heated to about 16-1700 degrees Celsius. Under these conditions, the graphite changes in a physicochemical process and becomes diamond. Diamond is the thermodynamically more stable form of carbon.

In this way, diamonds of breathtaking uniqueness can be produced - and without polluting the environment or endangering people in crisis regions.

Why we use lab grown diamonds

At Maren Jewellery, we have chosen to use synthetic Eco Diamonds from Diamond Foundry and Swiss Diamond Vision instead of natural ones for our jewelry.

Not only are they as pure and unique as natural diamonds, but their origin is 100% assured: our diamonds come from either Switzerland or America. Thus, our gemstones are 100% of conflict-free origin. In addition, synthetic diamonds are resource efficient. If 1ct of diamond is mined in the conventional way, up to 200 tons of earth have to be moved for this. Moving these masses costs an incredible amount of energy. Our diamonds are therefore much more environmentally friendly than natural diamonds. Only the high energy needed for the growing process is problematic - but Diamond Foundry thinks about that too, being a CO2 neutral company, just like Maren Jewellery.

Jewelry that fits our values

By choosing synthetic diamonds, we can ensure that we design jewelry that fits our values: Sustainable, Mindful and Responsible. Of course, on our product pages you can see which diamond we use for which piece of jewelry - either those from Diamond Foundy or from Swiss Diamond Vision. And best of all: our jewelry not only looks good on you, but also on our planet!
