12 CTW Emerald Lab Grown Diamond Tennis Bracelet

Lab grown diamonds are real diamonds created in a controlled environment using advanced technology. They have the same physical, chemical, and optical properties as mined diamonds—meaning they look, feel, and sparkle just the same. 

While natural diamonds are formed over millions of years beneath the Earth's surface, lab diamonds grow in just weeks or months using cutting-edge techniques.

Not at all. Lab grown diamonds are 100% real diamonds, unlike simulants such as cubic zirconia or moissanite. They are created using heat and pressure, just like mined diamonds, but without the environmental and ethical concerns of traditional diamond mining.

Lab grown diamonds are created using two methods:

High Pressure High Temperature (HPHT): Replicates the Earth's extreme heat and pressure where diamonds naturally form.A small diamond seed is placed in a chamber and exposed to over 1600°C and intense pressure, causing carbon atoms to bond and grow into a diamond crystal.

Chemical Vapor Deposition (CVD): A diamond seed is placed in a vacuum chamber filled with carbon-rich gases. With high heat and ionized gases, carbon atoms slowly layer onto the seed, growing the diamond crystal over time.

Both methods produce  real diamonds that are indistinguishable from mined diamonds—even by gemologists without specialized testing equipment.

Yes! Lab-grown diamonds test as real diamonds because they have the same chemical and optical properties as mined diamonds. Standard diamond testers that measure thermal and electrical conductivity will detect them as diamonds.

No, lab grown diamonds will not get cloudy over time. Like mined diamonds, they are made of pure carbon and maintain their brilliance forever. If your diamond appears dull, it likely just needs a quick cleaning to remove everyday dirt and oil.
