The Man Made Diamond USA Simulated Diamond vs. CZ and Moissanite
Our Simulated Diamonds are different from inexpensive CZ and Moissanite in several ways. These differences result in a superior diamond simulant that better resembles the qualities of a natural diamond.
The main difference is that an inexpensive CZ is a much softer and porous stone, thus making it very susceptible to chipping and scratching. CZ absorbs dirt and oils and becomes milky and cloudy in a short period of time and eventually it will appear yellowish and loose its fire and ability to disperse light. CZs are usually faceted in an attempt to mimic the natural brilliance of a diamond, but because of their softness, the faceting is very rounded, not sharp and crisp. The typical Cubic Zirconia is a very short-lived stone and mainly used for inexpensive fashion jewelry.
While Moissanite is beautiful in its own right, it has two main shortcomings. Chemically, it is made of silicon carbide and unlike a diamond; it has a different crystal structure and refractive index. It is hexagonal vs. cubic, which makes it doubly refractive - which is not a desirable quality in replicating a natural diamond.
For this reason, Moissanite jewels are cut along the optic axis of the crystal to different proportions and faceting as to minimize the effects. This cutting style makes it very noticeable and different from a diamond since the internal faceting is different. In particular, Moissanite round stones are oddly cut to allow a circular window in the center where it goes completely clear when viewed straight on, instead of reflecting light back, and no natural diamond would ever be cut like this.
Moissanite's higher index of refraction (brilliance) and much greater dispersion (fire) than either a diamond or a simulant, also makes it easy to the naked eye to distinguish it form a diamond. Where the best quality diamonds and diamond simulants have a D color (virtually colorless), a Moissanite stone has a slight yellow tinge to it that is very noticeable in indoor lighting and which also becomes more noticeable with increasing carat sizes.
In addition, square shapes in Moissanite like the princess cut and radiant cut; will show even more obvious tinting due to their lower brilliance as compare to rounds.
Man Made Diamonds' Simulated Diamond
Our Diamond Simulants are carefully crafted to be nearly flawless and colorless in every way. They resemble the same optical characteristics, have the ability to cut glass and can be shaped into all the same styles as natural diamonds. In most experts’ opinions, the Agape Diamond is a superior alternative to a natural diamond because for the same cut, clarity, color and carat of a natural diamond that would fetch tens of thousands of dollars, our simulated diamonds of VVS1 quality rating are a mere fraction of the cost.
Beware of Stone Coating (DLC) and other such marketing
In recent years, manufacturers have tried different ways to distinguish their products. Most companies sell a common CZ and put a coating on their product as a way to differentiate it. Sometimes the language used is "diamond infused" or "diamond hybrid" and the coating they are referring to is called "DLC", which means "diamond-like coating". This coating process has been around for years, and the "diamond" coating being referred to, as "amorphous carbon" is nothing more than pencil lead. When a stone is coated with amorphous carbon, the coating must be exceedingly thin as to be essentially non-existent. Otherwise, the stone would be discolored. Another technique is “vacuum sputtering” and “chemical vapor deposition” also known as “CVD” in which an extremely thin layer of metal oxide is coated onto the stones to create iridescence. Marketed as “mystic” the material is unlike DLC, in that it isn’t permanent. The metal oxide layer is also easily removed by abrasion.
Regardless of these innovations and processes which are all aimed to improve their refractive index and to achieve a diamond like signature under Raman Spectroscopy - a device that identifies an object’s crystal structure; the most important step in the manufacturing process is the final step – the cutting and polishing – which is what makes the difference between them.
The faceting and polishing is the most crucial aspect of the stone and here is where you get the different qualities. The amount and precision of facets cut into the stone is what determines the different qualities of diamond simulants. The fluorescence, fire and sparkle of the stone can only be achieve by the amount of light that refracts from within the stone and this can only be achieved by the faceting and polishing of the stone.
As a final note, because of their hardness and durability, our diamond simulants don’t require any special cleaners. The same as with natural stones, detergents and soap can leave a film on the stones, and so can skin oils. Using plain white vinegar or a mixture of ammonia and water will keep your jewelry always looking brand new.
