Diamond Nexus Diamond Simulants

Diamond Simulants are stones made in a lab that look and act just like a mined diamond. In other words, they are physically and optically identical. Chemically speaking, Diamond Simulants are created out of 10 elements, and mined diamonds are solely made from Carbon. The benefit of Diamond Simulants is that they are always internally flawless, colorless stones. This means that they will always be perfect stones and they also come with a lifetime warranty. Oh, and we almost forgot to tell you: Diamond Simulants are only a fraction of the cost of mined diamonds!

Mined Diamonds

Mined Diamonds come from the Earth. The process to dig up these stones has destroyed hundreds of forests and created a multitude of crater-like diamond mines throughout the world, not to mention the horrendous treatment of human beings who have endured torture or worse while being used as slave labor in the diamond mines. In addition to the devastated terrain, there is no guarantee that a mined diamond is a conflict-free diamond. Retracing the carbon-footprint of a mined diamond is near impossible. Mined Diamonds come with many variations- cut precision, color, and clarity. Because the supply of mined diamonds is controlled by the diamond cartels, the price of diamonds can be exorbitant.
