Synthetic and Man-made Diamonds vs Natural Diamonds

Round brilliant polished diamonds.We often get comments from customers asking why they should by a real diamond vs a man-made diamond. Their argument often involves the following points:

  • A man-made diamond is much cheaper than a real diamond
  • A synthetic diamond has more brilliance than a real diamond (particularly Moissanite)
  • A man-made diamond is almost as hard as a real diamond (paricularly Moisannite)

Well here is our typical answer to dispel a few myths…

A man-made diamond or synthetic diamond is in cases much cheaper than a real diamond, however they are well over priced for what hey are. Many years ago we saw the introduction of Cubic Zirconias which were cheaper than diamonds but still well over priced for what they were. They have now come down to their true value at about $5 for a bucket load of them. So the price argument becomes redundant, a man-made diamond will always fall back to its natural price, which is unfortunately about worthless. We see people come into our store all the time where they purchased a diamond many years ago for say $200 which the diamond is now worth say $5000. The Cubic Zirconia they bought years ago for $50 in now worth Nil.

The second point is the claim man-made/synthetic diamonds have more brilliance than a real diamond (particularly moissanite). The truth here is that they do, but diamonds have never claimed to have the highest refractive index on the earth. The beauty of the diamond comes from the unique refractive index that it does carry. Nice and brilliant, but it doesnt look like you have a disco ball or rainbow on your finger. So for the Moissanite manufacturer to claim that their product has a far higher refractive index than diamonds, is to claim their product looks nothing like a diamond, so why do they call it a synthetic diamond??

The last point is the hardness of Moissanite vs Diamond. In the official Mohs scale of hardness, a diamond carries the top level 10 out of 10 and Moisannite carries approx 9. This seems to be close, however the scale is not one of a straight line, rather it increases exponenitally. In simple terms, a diamond is up to 100 times harder than its nearest man-made or synthetic creation. Number 9 in the Mohs scale is closer to number 1 than it is to the top level 10.
