This solitaire engagement ring features a round center stone weighing 1 carat. The center stone is set in a traditional four prong setting and pinched center band. The band measures approximately 2 millimeters and weighs about 3.7 grams. The diamond will be certified by an independent laboratory such as IGI or GCAL. Lab-grown diamonds and naturally occurring diamonds share identical chemical and optical properties and are graded to the same specifications. The technology that produces lab-created diamonds replicates the conditions that create diamonds deep in the Earth's crust. With a much smaller carbon footprint and environmental impact than diamonds produced by traditional mining operations, lab-created diamonds are the perfect choice.
