Eco Synthetic Diamonds

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 partner Swiss Diamond Vision works with the HPHT process to produce lab-grown synthetic Eco Diamonds. HTHP stands for High Temperature, High Pressure. In this process, which is modeled on the natural formation process of diamonds, graphite-2H is placed in growth cells that are subjected to up to 70,000 bar pressure from three sides in so-called cubic presses. Graphite-2H is a natural manifestation of the chemical element carbon, which has a hexagonal crystal structure similar to a honeycomb. The interior of the growth cell is first loaded with catalysts and seed diamonds and heated to approximately 1600-1700 degrees Celsius. Under these conditions, the graphite changes in a physicochemical process and the black powder grows into a transparent diamond. Diamond is the thermodynamically more stable form of carbon.

The growth time for an approx. 1.5 carat diamond rough stone in white, blue or yellow color is about 50 hours. Through additional treatment, pink, green and red diamonds can also be produced. The Swiss Diamond Vision rough diamonds grown in this way are then cut in Antwerp into the beautiful gemstones we use in our jewelry. Both the diamonds produced by the CVD process and those produced by the HTHP process are in no way inferior to natural diamonds: they are identical to their natural counterparts in terms of appearance, hardness and chemical composition.

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!
