Our Technology: How We Make A Diamond Simulant
Diamond Nexus products, which include Diamond Simulants as well as synthetic rubies, emeralds, and sapphires, have only become possible in the last few years due to significant breakthroughs in chemical and materials engineering. This section of our site will take you through the creation process of our products step-by-step, and will also teach you how Diamond Nexus compares with other products available today.
Our leading product, the Diamond Simulant, is a revolutionary coated crystal that near perfectly recreates the optical and physical (how it looks and how it wears) properties of an earth-mined diamond. The patent-pending process to create this Diamond Simulant is complex, but ultimately worthwhile.
Significantly different from and superior to other competing products such as CZ and Moissanite, a Diamond Simulant will cut glass, is incredibly hard, and, like an earth-mined diamond, will last forever. No one in the world, including your jeweler, can tell that a Diamond Simulant is not a natural diamond without scientific testing.
The Diamond Simulant creation process
Your Diamond Simulant begins its life in a ceramic and carbon-fiber crucible, which is lined with a very technologically advanced phase-change material that is necessary to handle the enormous heat and pressure of the Diamond Simulant creation process. At extreme temperatures, approaching 4000 degrees, we mix a proprietary blend of elements in a very specific sequence and we bring them to a molten state called a "matrix". Highly specialized equipment is required, as the matrix is so hot it will destroy most containment mediums.
The matrix is then cooled in stages in a carefully controlled fashion. During this cooling process the crystals form and must be precisely monitored. Cooling too slowly will not produce crystal growth, while cooling too quickly will cause the crystals to shatter and fragment into tiny pieces.
After the matrix is cooled, the product is called a "boule", which is a solid object containing crystallized and non-crystallized material. The boule is broken up (actually with a big hammer) and the crystals are extracted. The crystals are a heavy, hard and molecularly dense material that to the eye closely resemble an uncut diamond crystal. The un-crystallized material is not wasted and is used again as a charge phase for the next run.
The crystals are then inspected for quality in a similar fashion to which rough diamonds are inspected and graded. A laser beam is passed through the crystal which highlights internal flaws and gives a guide for rough cutting.
Once rough cutting is complete, the Diamond Simulants are again sorted and moved on to the final cutting stage which is done in our Austrian fine-cutting facility. Due to the fact that after rough cutting, our crystals contain no inclusions or other flaws, the cutting process can be much more precise than for a natural diamond. (The cutters are not trying to work around and hide flaws.) This enables all of our Diamond Simulants to be cut to Ideal Cut Standards, which only about 15% of stones achieve in the diamond world. (This yields the desirable "Hearts & Arrows" pattern found in the finest cut mined diamonds).
