How to buy lab grown diamonds?
Lab-grown or lab-created diamonds are artificially produced in a laboratory, using advanced techniques that replicate the natural diamond formation process. They possess the same chemical, physical, and optical characteristics as mined diamonds. The two main methods are High Pressure, High Temperature (HPHT) and Chemical Vapor Deposition (CVD). These diamonds offer an ethical and environmentally friendly alternative to traditional mining, avoiding the associated conflicts and ecological impacts.
We have a 30-day return and exchange policy. If you have any questions or need instructions regarding returns, please contact us. Please ensure that you return the ring with its original packaging.
Yes, we offer IGI certification for lab-grown diamond rings that are over 1 carat. For diamonds below 1 carat, certification is available for an additional fee of USD 94. We provide these certificates to ensure transparency and authenticity, which can also be used for jewelry appraisal purposes.
Our experienced grader meticulously selects lab-grown diamonds, which, while slightly more expensive, are excelllent in cut and appearance. These diamonds, chosen from a larger collection, are of superior quality.

Moissanite may appear dull if dirt accumulates on or under the stone. However, once cleaned, it will return to its original, sparkling appearance.
Our rings are exclusively crafted from real, solid gold, silver, and platinum. We do not use plated metals for ring making. Each ring features a purity stamp inside the band to indicate the metal's authenticity.

Did you know that lab-created diamonds, sometimes called synthetic diamonds, are made in controlled environments that mimic how diamonds naturally form deep in the Earth? These best lab grown diamonds are carbon atoms structured exactly like natural diamonds, giving them identical optical and chemical qualities. Scoring a perfect 10 on the Mohs scale, just like mined diamonds, their only difference is where they come from. They go through the same growth, cutting, and polishing steps as their natural counterparts, offering a variety of colors and clarities.
Lab-grown diamonds and natural diamonds differ primarily in their origin. Natural diamonds are formed over billions of years under the Earth's crust through extreme pressure and heat. They are then mined from the earth.
Lab-grown diamonds, on the other hand, are created in controlled laboratory environments using advanced technological processes like High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD). These methods replicate the natural diamond-growing conditions.
While both types of diamonds are chemically and physically identical, lab-grown diamonds offer a more ethical and affordable choice, reducing environmental impact compared to traditional mining.
