WHAT IS A LAB GROWN DIAMOND?
Lab grown diamonds – also known as synthetic diamonds, man-made diamonds, engineered diamonds, or cultured diamonds – are (you guessed it) made in a lab. Since diamonds consist of carbon atoms arranged in a crystal formation, scientists can create these diamonds by isolating carbon and layering it onto itself.
They do this one of two ways. There’s the High-Pressure High-Heat (HPHT) method, which mimics the conditions that create diamonds deep beneath the earth’s surface, and there’s Chemical Vapor Deposition (CVD), which uses high heat to break carbon atoms free from their molecules, letting them settle like snow onto a flat surface until a diamond forms. A mined diamond (left) and a lab grown diamond (right) can appear identical to the naked eye. Can you tell the difference?
Lab grown diamonds have the same physical, chemical and optical properties as mined diamonds. In fact, even industry experts cant always tell the difference without special equipment that scans for crystal patterns and impurities. For example, if the diamond contains nitrogen, it likely came from the earth.
Pros and Cons of Lab Grown Diamonds
If lab grown diamonds are not simulants, that raises the question: Is there really a difference between buying a lab grown diamond and paying more for a natural one?
The answer is yes. Here are few benefits and drawbacks of lab grown diamonds, compared to their mined counterparts.
- Lab grown diamonds will cost 30-40% less than a natural diamond of similar size, color and clarity
- Lab grown diamonds do not require mining, which degrades the environment and has been known to historically put workers in dangerous or unsanitary conditions. While recent measure taken against the production and sale of conflict diamonds with the Kimberly Process has helped determine a diamond’s origin, it does not account for human rights factors
- Since these diamonds have the same exact atomic makeup as natural diamonds, lab grown diamonds have skyrocketed in popularity in the last five years, with even natural diamond behemoths like DeBeers getting in on the lab grown game
- Because lab grown diamonds have no supply constraints, their value will continue to depreciate, which will impact resale value and make it more costly to upgrade in the future
- Diamond labs are run by well-funded corporations in developed countries, whereas your purchase of a natural diamond supports people who depend on mining for income, creating about $4 billion in revenue for employees and $6.8 billion through the economic ripple effect in their communities
- While lab grown diamonds circumvent environmental issues with mining, they create sustainability problems of their own. The heat and pressure needed to create a lab grown diamond demands huge amounts of energy
