With an era of high-end technologies the jewelry market seems to be flooded with many diamond alternatives. On the one hand, it’s always a great thing to have a wide choice for customers to decide, but on the other there can be a sort of confusion for mere customers who are less competent in this sphere.
Indeed, a term of synthetic or man made diamonds is now often applied to diamond simulants so when customers see “high-quality man made diamonds simulants” offered at online store they can be mislead by such controversial combination. In this regard we found it useful to clarify the term of man made diamonds and diamond simulants.
Synthetic, lab grown and man made diamonds are real diamonds comprising all the features of mined diamonds but for their age as far as synthetic diamonds don’t demand thousands of years for their formation, 5-7 days is enough to synthesize them in the laboratory. Speaking about the price, man made diamonds are not cheapie but they are less expensive than natural diamonds, about 20%-40% cheaper. They are usually referred to as affordable. They are not fake, faux or brummagem. They are real diamonds what can’t be said about simulants.
Diamond simulants have nothing to do with diamonds at all, but as far as they optically resemble diamonds and have bright luster diamonds are valued for they are called diamond simulants. However, they are usually CZ posed as cheaper diamonds. They are normally very inexpensive and set in 14K gold. While diamonds are wearproof, longlisting (actually everlasting) , fadeless and scratchless, Cubic Zirconia is unable to imitate all these properties. So, diamond simulants can’t equally substitute diamond gems.
One of the manufactures of diamond simulants is Nexus Diamonds and these are some FAQs to clarify the origin of Nexus diamonds:
What are Diamond Nexus lab-created stones made out of, and how are they different from natural diamonds?
Mined diamonds are a crystalline substance made out of carbon. Diamond Nexus Gemstones are a crystalline substance that is very complexly engineered and chemically different from a mined diamond; they contain carbon, but very little of it. Optically (how they look) and physically (how hard they are, how they wear and last, etc) they are nearly identical to mined diamond and no one in the world can tell them apart visually by eye alone, but the chemistry is completely different. The question we ask our customers to consider is if you want to pay thousands of dollars for chemistry.
Why can’t you make your stones with just carbon?
Actually we can, however, currently the cost of making white (clear) diamonds in the lab in sizes larger than a half carat exceeds the cost of mining them by a pretty substantial margin. Trust us; we are working on the problem. We do currently sell pure carbon man-made diamonds, but only in a canary yellow color. They are priced at less then half the cost of a canary colored mined diamond.
I heard that Diamond Nexus stones are just regular CZ. Are they?
No, actually they’re not. Sorry to get a little technical here, but there’s no way around it:
Common CZ generally contains two elements. Zirconium and yttrium. While a Diamond Nexus also contains zirconium, it also contains hafnium, gadolinium, cobalt and other elements. The elements in a Diamond Nexus are tremendously more expensive then the elements is a CZ. This results in a stone that is harder, tougher and significantly heavier then a CZ. In fact, the easiest way to differentiate a Diamond Nexus gemstone from a CZ is simply by weighing it. The Diamond Nexus stone is approximately 20% heavier for an equal size stone. (DN Mark IV and Mark V) This material is then coated in a patent applied for material which contains AL203 corundum and other elements to a thickness of approximately one micron (DN Mark V stones. DN Mark IV, 120 +/- nanometers). This coating is bonded to the substrate on the molecular level and will never wear off in normal use. The coating significantly lowers the porosity of the stone and renders it nearly impervious to any degradation. The coating also brings the optical properties of the stone almost perfectly in line with mined diamond. So, while the manufacturing process of a Diamond Nexus shares some of the same manufacturing process of CZ, there are many more steps, elements and treatments involved in a Diamond Nexus simulant. The result is a different stone with different, better properties.
