What is a NSCD Simulated Diamonds?
The American Gem Trade Association defines a Diamond Simulant as: “A man-made single crystal, which can be manufactured with different materials and designed to simulate the appearance, but not duplicate the characteristic properties of a natural gemstone.” There are several brand names of Simulated Diamonds in the market today. Each one having its own claims on how they simulate a real diamond. Regardless if you use Silicon Carbide, Zirconium Oxide, Aluminum Oxide or any other material as the basis to form the crystals, because they are not natural occurring stones, they are all considered “ Simulated Diamonds”.
The NSCD Simulated Diamond
Natural Diamonds attribute their colored hues to imperfections within the stone and their value is directly dependent upon the clarity, color, carat weight and cut quality of the stone. NSCD Simulated Diamonds are carefully crafted to be nearly flawless and colorless in every way. They are cut and faceted to achieve maximum brilliance without any imperfections; they resemble the same optical characteristics, and can be shaped into all the same styles as natural diamonds. The only difference in many experts’ opinions is the price. For the same clarity, cut, color and carat of a natural diamond that would fetch thousands of dollars, our simulated diamond of VVS1 quality rating are just a mere fraction of the cost. Because of their superior quality, the NSCD Diamond is regarded as the Premier Simulated Diamond in the world.
How are NSCD Simulated Diamonds Made?
A Diamond Simulant is manufactured with a process called the “skull melt” in which the materials heat up from the inside outwards. The outside remains relatively cool while the inside melts, forming its own outer crust or “skull”. Only with extreme heat is the “preferred cube form” obtained and a metal oxide stabilizer is added to the process to ensure isometric cubic crystals. When the heat is switched off, the product then cools under rigidly controlled conditions and hardens. NSCD Simulated Diamonds are scaled an 8-8.2 on the Mohs hardness scale. As it hardens, the solid crystals are formed. Because they are made in a controlled environment, the crystals are also perfect in structure, without feathers or inclusions and since they are solid and not composed of layers, they are almost as hard as a natural diamond (8-8.2 on the Mohs Scale). Due to their hardness and clarity the crystals can be cut using the same proportions used in cutting fine diamonds. Faceting too, is intensive and precise, creating facets and mimicking the brilliance of diamonds.
The brilliance and hardness of our finished crystals can vary slightly, so measurements for color, hardness and gravity are given in ranges.
Color: D – F: (on the diamond scale)
Hardness: 8-8.2 (Mohs hardness scale)
Specific Gravity: (5.8 – 6.0)
Crystal Form: (Isometric)
Refractive Index: (2.20)
The NSCD Difference
The faceting and polishing is the most crucial aspect of any stone. Here is where you get the different qualities. The amount and precision of facets is what determines the different qualities of diamond simulants. The fire and sparkle can only be achieved by the amount of light that refracts from within, and this can only be achieved by the faceting and polishing. That’s why the NSCD Simulated Diamond is one of the Most Brilliant Simulated Diamonds.

Thank you Port City Jewelers. This ring is absolutely beautiful. It is clean, clear, the dispersion is absolutely breath taking. It sparkles in the house, with no lights on. My goodness. I was hoping it would be beautiful, but when I opened it I was speechless. My husband opened it first and he said I think you have found your favorite ring.
If you are looking for the WOW factor, this is it.
Port City Jewelers, I buy jewelry, and you are my new Jewelry store. Thank you so much. I love this ring set. There are not enough words. Judy Meade
