NSCD Simulated Diamonds have now been discontinued by the supplier and are no longer in production.  Please be advised that any retailers claiming to sell NSCD Simulated diamonds are not selling true NSCD Simulated diamonds!!

So what do I do now?  

Well there are plenty of great alternatives out there in the market!  One is our Eternal Moissanite gems!  Our Eternal Moissanite gems are made of SicC (Carbon and Silicone).  They are lab grown gems and faceted just like a diamond is faceted!  The fire and brilliance of our Eternal Moissanite and any other Moissanite brand out there is FOREVER!  They never fade or loose their color!  They are even more durable than sapphires on the Mohs scale!  Diamond is the hardest known substance to man at a 10 on the Mohs Hardness Scale.  Moissanite is a 9.5 on the Mohs Scale.  Sapphire is a 9 on the Mohs Scale!  Moissanite is really the best alternative to diamonds!  PERIOD!

NSCD SIMULATED DIAMONDS VS. REAL DIAMONDS 

There are many reasons why people prefer NSCD Diamonds over Natural Diamonds!  Here are just a few.

1. They are A LOT less expensive than natural gem quality diamonds. 
2. The average consumer can afford a larger simulated diamond or that DREAM RING!
3. They are all high quality stones VVS1 comparable in clarity and D-F comparable in color
4. BEST OF ALL, they are CONFLICT FREE Stones.

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)

Dispersion: (0.056)

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.
