• Origin: CVD diamonds are created in a laboratory setting rather than being mined from the Earth. They are considered lab-grown or synthetic diamonds.
• Composition: CVD diamonds have the same chemical composition as natural diamonds, consisting of carbon atoms arranged in a crystal lattice structure.
• Growth Process: In the chemical vapor deposition process, a diamond seed (a tiny piece of diamond) is placed in the deposition chamber. The chamber is then filled with the carbon-rich gas mixture. Under specific conditions of temperature and pressure, the gas mixture is activated, and carbon atoms are deposited onto the diamond seed, gradually growing the diamond layer by layer.
• Physical Properties: CVD diamonds possess the same physical properties as natural diamonds. They exhibit exceptional hardness (10 on the Mohs scale), high refractive index, excellent thermal conductivity, and strong light dispersion.
• Color and Clarity: CVD diamonds can be produced in a range of colors, including white, yellow, brown, and even fancy colors like blue and pink. The clarity of CVD diamonds can vary, with some stones being nearly flawless while others may contain visible inclusions.
• Size and Shape: CVD diamonds can be grown in various sizes and shapes, offering flexibility in jewelry design and applications.
