The laboratory-grown diamonds that are GCAL certified are independent gemstones that have been evaluated for quality, authenticity, and performance at Gem Certification & Assurance Lab. Unlike the normal evaluation report on the diamonds, the GCAL certification does provide a description of the cut, brilliancy, light performance, and optical symmetry of the diamond. Be it round, oval, princess, cushion, emerald, radiant, pear, marquise, heart, or asscher shape, there is a broad selection of GCAL certified lab grown diamonds in various sizes starting from 0.30 carats up to 5.00+ ct. Most people prefer purchasing excellent cut diamonds due to their exceptional brilliance and light performance.

Each GCAL-certified lab grown diamond is produced in an ethical process without damaging the environment through the conventional process of diamond mining. There are various filter options available in our range of diamonds, such as shape, carat weight, color, clarity, cut, price, and certification. You can also browse for different shapes of diamonds using the individual pages we have created specifically for diamond shapes. Every diamond is thoroughly examined by us for its beauty and value.

Loosegrowndiamond offers some of the best GCAL-certified lab grown diamonds that come at a reasonable price and are of high quality. Whether you are looking for beautiful diamonds to make a diamond engagement ring, earrings, a pendant, or any other piece of jewelry, you will get ethically sourced and GCAL-certified diamonds that sparkle brilliantly.
