Frequently asked questions

Tell me more about Cultured / Lab-Created Diamonds.

Lab-created diamonds are genuine diamonds that are produced in a laboratory instead of being mined from the earth. They are made of pure carbon, the same material as mined diamonds, and have identical physical, chemical, and optical properties. Gemologists or other experts cannot tell them apart. Lab-created diamonds are just as hard and durable as mined diamonds, and they will last forever, making them an excellent choice for jewelry that will be worn every day. Furthermore, lab-grown diamonds are a more ethical and sustainable choice as they don't contribute to the negative environmental and social impacts associated with mined diamonds.
