Lab Diamond Rings FAQs

Lab diamond rings are made with diamonds created in high-tech labs. These diamonds have identical physical, chemical, and optical properties to natural diamonds, with a comparable appearance and quality.

Lab diamonds are created using two advanced methods: HPHT (High Pressure, High Temperature) and CVD (Chemical Vapor Deposition). Both replicate the natural formation process of diamonds in a controlled lab environment.

Lab diamonds offer exceptional value, are eco-friendly, and ethically produced. They cost 30–50% less than mined diamonds of the same quality, without compromising brilliance or beauty.

Absolutely. Lab diamonds score a 10 on the Mohs hardness scale, just like natural diamonds. They are perfect for everyday use and last a lifetime with proper care.

Clean your ring regularly with mild soap and warm water, and use a soft brush to remove buildup. For best results, have it professionally cleaned once a year. Click here to learn more detailed cleaning methods.

We offer a wide range of cuts, including round, oval, emerald, cushion, princess, and pear-shaped lab diamonds—each cut to maximize sparkle and brilliance.

Most lab diamonds are colorless or near-colorless (D–H), but we also offer fancy-colored options like pink, blue, and yellow for a unique look.
