What is a lab-grown diamond?

Lab-grown diamonds (commonly known as LabGlo) are artificial diamonds that are artificially synthesized, so naturally, their composition and properties are exactly the same as those of diamonds.

There are two ways to generate

①HTHP method (high temperature and high pressure method)

This is produced by recreating the same environment as a natural mine in a laboratory, and subjecting cylindrical carbon to pressures of around 55,000 atmospheres and temperatures of over 1,400°C.

This is the traditional method of creation, and the lab-grown diamonds created using this method tend to be small and contain inclusions, so they are often used for melee diamonds.

②CVD method ( chemical vapor deposition method )

This is a method that is often used recently to produce large lab-grown diamonds. Thinly sliced ​​diamonds are used as seeds to grow diamonds in layers, and the diamonds grow little by little by applying microwave energy to methane gas containing carbon. The type and amount of impurities in the diamonds produced in this way can be precisely controlled, making it possible to produce large diamonds with high purity.

In the past, the investment required for manufacturing machinery was very high, so only a limited number of companies were able to produce it, but recently many manufacturers have become able to produce it, and prices have been able to be kept down.

About the price of lab-grown diamonds

The current market price is roughly 1/3 to 1/2 of that of natural diamonds. In recent years, the number of manufacturers capable of producing lab-grown diamonds has increased dramatically, and prices have fallen by approximately 70% compared to three years ago. As a result, many brands have begun to handle them.

Recently, the number of manufacturers handling this product has increased, and it has gradually become more well-known, so it is being accepted by everyone. As a result, demand has increased rapidly, and the price has gradually risen.

However, in the long term, as more manufacturers become able to produce them, they are expected to gradually become more affordable.

What is Moissanite? Is it a fake diamond?

Moissanite is often mistaken for an artificial diamond, but to be precise, LabGlo diamonds are artificial diamonds, while moissanite is not.

Diamonds and artificial diamonds are aggregates of carbon.

Moissanite is a substance called silicon carbide, which has similar chemical composition and properties to diamond.

However, its dispersion rate is actually 2.5 times that of diamonds, making it more brilliant than diamonds.
In addition, its toughness, an index of hardness, is higher than that of diamond, making it less likely to break than diamond.

This makes it an excellent gemstone to be passed down through generations.

Natural moissanite is a meteorite and is therefore considered rarer than natural diamonds.

Moissanite does not occur naturally on Earth, so all moissanite used in jewelry is synthetic.

In fact, thanks to human technology (formerly patented by a US company), moissanite is now easier to produce than lab-grown diamonds.

This allows us to provide a stable supply of high-quality products, and they are traded at prices approximately 1/10 or less of those of natural diamonds of the same grade and carat weight.

As ethical jewelry

Both lab-gro diamonds and moissanite started in Europe and the United States and are attracting a great deal of attention globally because they do not involve mining of the earth, do not address child labor issues, and do not fund conflicts.

Another very important point is that the amount of electricity used to produce moissanite is about 1/100 of that used to produce lab-grown diamonds, making the manufacturing process very ethical and putting less strain on the earth.

For these reasons, moissanite has recently become the choice of many European and American celebrities.

Why not choose moissanite jewelry to help pass on a beautiful earth to the next generation?
