Lab grown diamonds are real diamonds created using advanced technology that mirrors the conditions under which diamonds form in nature. Because they share the same chemical composition, sparkle, and durability as mined diamonds, lab grown diamonds have become a popular choice for engagement rings, wedding jewelry, and everyday fine jewelry. They are graded using the same industry standards, making it easier to compare quality and choose a diamond that fits your style and budget.

At Brilliant Earth, our collection of lab grown diamond engagement rings and fine jewelry brings together exceptional craftsmanship, beautiful design, and a more thoughtful approach to sourcing. Each lab grown diamond is selected for its brilliance and quality, giving you the confidence to choose a piece that reflects your style, values, and budget. Whether you are searching for a timeless solitaire or a distinctive modern setting, Brilliant Earth makes it easy to find a lab grown diamond that feels personal, meaningful, and made to last.

Lab grown diamonds are created in a laboratory rather than deep within the Earth. They have the same sparkle, composition, and durability as natural diamonds, which form underground over millions of years.
The only difference between lab grown and natural diamonds is their origin. Natural diamonds are formed deep below the Earth’s surface over billions of years, while lab grown diamonds are created in a laboratory. Despite their different origins, both lab and natural diamonds are identical in chemical composition and physical appearance.
Lab grown diamonds are created in controlled environments, which allows for better quality control and supply chain transparency. Additionally, lab diamonds appeal to environmentally conscious consumers as their sustainable sourcing methods cause minimal disruption to the earth.
Yes, lab grown diamonds are independently graded and certified by major gemological laboratories, such as the IGI. Each certificate details the diamond's carat weight, cut, color, and clarity, so you can shop with confidence. Brilliant Earth's lab grown diamonds come with a grading report you can review before you buy.
