At Diamante de Laboratorio, we have been dedicated to buying and selling diamonds for over 25 years. We started as intermediaries for mined stones and today we work almost exclusively with lab-grown diamonds, because they offer the same gemological quality at a much more accessible price and a more ethical and sustainable origin. We offer a catalog of over 700,000 diamonds, all certified and laser-inscribed, as well as direct and close advice whether you are buying as an individual or if you are a jeweler. Getting to know Diamante de Laboratorio means knowing exactly who is behind each stone you purchase and why you can trust its certification.
Over 700,000 certified diamonds at your disposal
We offer you a catalog of over 700,000 lab-grown diamonds at the best market prices. Each stone comes with its gemological certificate and is laser-inscribed on the diamond itself, so its identification is always verifiable. This combination of stock volume and independent certification allows us to offer you real options for any budget and objective, from an engagement ring to an investment or a jewelry store's inventory.
Choose your diamond by cut, color, clarity, and certificate
Use the search filters to narrow down your search by size, color, clarity, and certificate type, IGI or GIA. You can also select fancy color diamonds if you want something other than classic colorless diamonds, such as a blue, pink, yellow, or black diamond. And if you know the shape you want, you can filter by cuts like round, princess, oval, emerald, pear, or heart, among others.
GIA and IGI Certification and laser engraving
All our diamonds come with a GIA or IGI certificate, the two leading gemological laboratories. The report details the actual characteristics of the stone, cut, color, clarity, and carat weight, and its number allows for verification. In addition, laser engraving on the diamond itself physically associates each stone with its certificate, an extra guarantee that what you buy exactly matches what is described.
How we advise you before buying
