Natural diamonds cost more due to their rarity and the complex geological processes that form them. These gemstones, especially larger diamonds with exceptional color and clarity, are incredibly rare. They are created over billions of years under extremely high pressure and temperature deep within the Earth’s crust. This scarcity makes natural diamonds highly valuable in the diamond market and determines the price difference between lab-grown and natural diamonds.
On the other hand, lab-grown diamonds (also known as synthetic diamonds, lab-created diamonds or man-made diamonds) can be produced in virtually unlimited quantities, through Chemical Vapor Deposition (CVD) or High Pressure High Temperature (HPHT)processes. With modern technology, lab diamonds can be created in any carat weight, color grade, or clarity grade, making them more affordable than natural stones. The price of lab-grown diamonds is primarily determined by production costs and profit margins, rather than rarity.
When comparing the two types of diamonds on the market, there is also a difference in diamond price trends over time. Unlike natural diamonds, which are a finite resource, lab-grown diamonds do not appreciate in value over time. In fact, as production processes become more efficient and competition increases, the value of lab-grown diamonds tends to decrease. Historically, natural diamonds have shown an average annual appreciation of about 3%, making them a stable, long-term investment with resale value.
For those seeking a truly unique, rare, and enduring diamond engagement ring or piece of jewelry, natural diamonds are an exceptional choice. They not only hold their value but also symbolize a timeless connection to the Earth’s history and natural beauty.
