Are Lab-Grown Diamonds Really That Different?

Contrary to the prevailing notion, not all diamonds are formed naturally by years of crystallization. Many diamonds available today in the market are formed through an artificial process in laboratories.

They have a striking resemblance with natural diamonds, so much so that it is impossible to tell which is which, despite the use of technical equipment (like a loupe). Seasoned gemologists and experts can’t tell the difference either.

Here’s a little introduction about how the two types of diamonds differ. It’ll help you understand what you are signing up for when (and if) you decide to purchase a lab-grown diamond.

The Formation

Natural Diamonds:

Diamonds are natural allotropes of carbon. Diamonds are extracted from vertical pipe-like source rocks while coal is mined from horizontal sedimentary rocks.

Natural diamonds are either molded when an asteroid strikes the surface of the earth or when a volcanic eruption expels magma with diamond fillings. It takes years of heat and pressure to fashion diamonds out of carbon.

Lab Grown Diamonds:

Lab diamonds resemble natural diamonds in all possible ways – physically as well as chemically. There are two major processes used to grow lab diamonds; the High Pressure High Temperature (HPHT) technique and Chemical Vapor Disposition (CVD) process.

For HPHT, a pressure of around 5Gpa is applied to a carbon-containing chamber and it is heated up to 1500 degrees. For CVD, carbon and hydrogen gasses are allowed to enter a chamber where they are energized to form a diamond.

The lab-grown diamonds are highly scratch-resistant and thermally conductive.

Effect on the Environment

Natural Diamonds:

Natural diamonds are formed by nature and they have no environmental impact as they are part of the natural process. However, their extraction process includes a certain level of environmental footprint.

The diamonds are extracted by using heavy machinery that produces extensive pollution. Further, to reach the diamond mines, sometimes lakes, ecosystems, and human population needs to be removed from the extraction site.

Lab Grown Diamonds:

Lab-grown diamonds claim to have no environmental impacts as they are not extracted. Nonetheless, critics have argued that diamond laboratories do not share all the data of the processes they use, saying the growers use raw material extracted from the ground. Thus, they are in no way different from extracted diamonds.

Where to Find?

Natural Diamonds:

There are around 36 countries where natural diamonds have been found. The list is available with the GIA. Apart from natural diamonds, micro-diamonds, a rare species of the former allotrope, have been found in China, Japan, US, and Norway.

Lab Grown Diamonds:

Most lab facilities for growing diamonds are available in Europe and the US, but many other labs are now being established to cut down costs.

Prices

Natural Diamonds:

The prices of natural diamonds vary due to several characteristics like color, clarity, carat, and cut. The prices are stable, making them a suitable gem for investment. A vast majority still prefers natural diamonds because of their longevity, their symbolic eminence, and sheer brilliance.

Lab Grown Diamonds:

The prices for lab-grown diamonds vary country to country. The diamonds are synthetic in nature and, therefore, do not have the same price as natural diamonds.

Moreover, as more diamonds are now being created artificially, the price of synthetic diamonds is falling. They share the same brilliance as that of natural diamonds but due to the abundance of artificial diamonds in the market, they do not have the same prices.
