Your Diamond’s Ethical OriginsLab Created

Lab created diamonds, also known as cultured diamonds, are grown in highly controlled laboratory environments using advanced technology. Our lab created diamonds have the same physical, chemical, and optical properties as mined diamonds. Since no mining is necessary to produce these gemstones, they are a responsible choice. Our lab diamonds are tested by an independent grading laboratory to confirm their lab created origin.

In the 1950s, scientists discovered how to harness the power of nature, replicating the conditions found deep below the earth to create real diamonds in the lab without mining impact. These remarkable gemstones have the same chemical composition, durability, beauty, and sparkle of a mined diamond. In fact, they are literally indistinguishable. Our unique, lab grown diamonds have been certified by independent diamond grading labs.

Brilliant Earth gives back to help build a brighter future in mining communities and in the communities we operate. We also donate to programs that are dedicated to improving human rights and environmental practices in our industry, including Feeding America, the Rainforest Alliance, and the NAACP Legal Defense and Educational Fund.

The Four C’s of Your Diamond

diamond size: 0.39 ct

The carat is the unit of weight of a diamond. Carat is often confused with size even though it is actually a measure of weight. One carat equals 200 milligrams or 0.2 grams. The scale below illustrates the typical size relationship between diamonds of increasing carat weights. Remember that while the measurements below are typical, every diamond is unique. Learn More

cut: Very Good

The cut refers to the angles and proportions of a diamond. The cut of a diamond - its form and finish, its depth and width, the uniformity of the facets - determines its beauty. The skill with which a diamond is cut determines how well it reflects and refracts light. Learn More

color: D

Color is the natural color visible in a diamond and does not change over time. Colorless diamonds allow more light to pass through than a colored diamond, releasing more sparkle and fire. Acting as a prism, a diamond divides light into a spectrum of colors and reflects this light as colorful flashes called fire. Learn More

clarity: VS1

A diamond's clarity refers to the presence of impurities on and within the stone. When a rough stone is extracted from carbon deep beneath the earth, tiny traces of natural elements are almost always trapped inside and are called inclusions. Learn More
