Certified Lab-Grown
Diamonds Houston

Houston’s lab-grown diamonds start at Sethi’s Fine Jewelry. Every stone in our Voss Road showroom is certified and priced 20-30% less than a comparable natural diamond. Come see and compare them side by side, no appointment required.

Lab-grown diamonds are real diamonds created in controlled laboratory environments using two primary methods: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD).

What Is a Lab-Grown Diamond?

When discussing lab-created diamonds, a common inquiry is “Are they real, high-quality diamonds?”

The answer is indeed yes! Also known as lab-grown or man-made, these diamonds only differ in their origin. A lab-made diamond is “grown” at a lab with technology that replicates the natural growth process. Moreover, it results in a diamond that is visually and physically the same as one grown beneath the Earth’s surface.

The most important thing to understand? These diamonds are not fake, not cubic zirconias. While some people call them “synthetic diamonds,” that is not technically correct. When comparing it with a simulation, it becomes evident which one is the genuine.

The Benefits of Man-Made Diamonds

  • Competitive Prices
    No diamond is free, but tighter supply chains mean that lab-grown diamonds in Houston, TX, are often 20-30% less expensive than natural diamonds.
  • Eco Friendly
    Diamond mining disturbs a great deal of land and creates thousands of pounds of waste.
  • Ethically Sourced
    Lab-grown diamonds don’t exploit workers or cause injury, whereas mining has been known to harm workers.

How Are Lab-Created Diamonds Made?

To carry lab-grown diamonds Houston trusts, we source them from certified suppliers. These diamonds originate from the carbon seeds of natural diamonds. Through either a special process or intense pressure and heat, they use advanced technology to imitate the natural formation of a diamond.

Lab-made fancy colored diamonds are produced when trace elements are present during the growth phase, similar to how it happens in nature. In both white and fancy-colored lab-grown stones, the exact composition of the trace elements may differ. However, the only way to tell the difference between a lab-grown and natural diamond is by using specialized equipment to detect the distinctions.
