However true chocolate diamonds, which have a stronger hue than found on the normal diamond color [...]
Moissanite jewelry is a popular choice for many consumers looking for an alternative to more expensive diamond jewelry. A beautiful stone in its own right, Moissanite is similar enough to a diamond that it can be used in place of the more expensive stone. It pays to do your research though, and the question of [...]
While lab created diamonds are most well known for their applications in jewelry, there are many other uses for these fascinating products of modern science. One of the most exciting among these uses is the possible applications in the next generation of computer chips! Diamonds have several properties that lend themselves extremely well to use [...]
I wanted to take a look at some more common questions about lab created diamonds in this article. There is a lot of interest in the comparison between real and lab diamonds, which is very understandable. After all, if a lab diamond has the exact properties as a real one, why wouldn’t you buy it?! [...]
In this article, I want to take a look at some common questions that I have heard people asking about lab created diamonds. Because of the lower price of created diamonds, there is growing interest in these gems as an alternative to a mined stone, so it is understandable that people want to know all [...]
The synthetic diamond industry has grown and advanced to the point where diamonds can be created fairly affordably on demand. As diamonds are composed entirely of heated and compressed carbon, it is possible to use the carbon from ashes (or hair, which is high in carbon) to create a small but brilliant memorial diamond with [...]
The term Russian diamonds conjures up some romantic images. The history and culture of the country, at least from what is shown in western media, is of secrecy, invention, and outlandish technology. Mixing these themes with the romantic ideas of diamonds as possessions of the fabulously rich and wealthy, leads to some dramatic mental images [...]

“How many carats?” is often the first question you are asked about a beautiful new diamond. The term ‘Carat’ is the most common term for describing the size of a stone, whether a natural or man made diamond. One metric carat weighs 200mg – one fith of a gram.
In this article we’ll be taking a look at a wide variety of simulated diamonds. These are also known as synthetic diamonds, so called because they “simulate” the look of the real thing. And I might add that they do this quite well. A simulated diamond is very different from a true lab created diamond. [...]
It is very important to understand the difference between lab created diamonds (and other created gems) and their imitation counterparts. Unfortunately, many dealers sell the latter under the banner name of “lab created” but this is in fact untrue. This is because they do not fit the definition of being made of 100% of the [...]
They say “Diamonds are a girls best friend”, but are they really a friend of the environment and of the people that mine them? Are they really necessary when there are perfectly adequate substitutes which are made from exactly the same material and virtually undetectable with the naked eye?
Modern lab created diamonds are primarily produced by Chemical Vapor Deposition (CVD) when a very hot gas containing carbon is deposited into a chamber at high temperature and pressure.
In the HPHT process, small diamonds are used as seeds. Graphite is dissolved in a molten metal at high pressure, and slowly precipitates as new diamonds.
