Are lab-grown diamonds real?

Yes! Lab-grown diamonds are 100% real diamonds. They are chemically, physically, and optically identical to mined diamonds, offering the same stunning brilliance, fire, and durability. The only difference is their origin. While mined diamonds are formed naturally over billions of years, lab-grown diamonds are created in advanced laboratories using cutting-edge technology that replicates the natural diamond-growing process.

Lab-grown diamonds are an ethical and sustainable alternative to mined diamonds, as they avoid the environmental impact and ethical concerns associated with traditional diamond mining. They are also an excellent value, often allowing you to get a larger or higher-quality diamond for the same budget, or save thousands of dollars to invest in real assets like the S&P 500, put a down payment on a house, contribute to a savings account, plan for your future child’s college tuition, or even take her on the honeymoon of a lifetime. With lab-grown diamonds, you can save significantly while still getting a stunning, high-quality diamond free from ethical concerns.

At Benz & Co Diamonds, we exclusively use the top 5% of the highest-quality lab-grown diamonds, ensuring you receive a perfect quality diamond that meets the highest standards and comes at the best price guaranteed. We only use diamonds in the top three color grades: D, E, or F color and only very clean diamonds with VS1 clarity and above. Additionally, we sell only Excellent Cut diamonds; however, not every Excellent Cut diamond is truly perfect. Some manufacturers cut corners to save on carat weight, resulting in noticeable imperfections such as large bow ties or dark areas. These diamonds do not pass our strict quality control standards.

Thanks to our six decades of expertise in the natural diamond industry, we have the knowledge to identify and eliminate diamonds with blue or grey overtones, as well as poorly cut diamonds that compromise brilliance and beauty. This expertise ensures that every diamond we sell is free from such imperfections and meets our exacting standards.

We are also proud to share that, since 2022, our jewelry manufacturer has been the same manufacturer trusted by the most prestigious jewelry brands in the world. This ensures that every piece of jewelry we create is of the highest quality and finish available, far superior to the commercial craftsmanship typically found in traditional stores.

Whether you're drawn to their beauty, ethical advantages, or exceptional value, lab-grown diamonds are a smart and modern choice for your engagement ring or fine jewelry.
