Lab-Grown Diamonds

Our commitment to authenticity extends to our collection of lab-grown diamonds. Each lab-grown diamond available at London Diamond Exchange comes with either a GIA (Gemological Institute of America) Certificate or an IGI (International Gemological Institute) Certificate—both of which are respected as gold standards in diamond grading. These certificates provide a comprehensive assessment of the diamond’s quality, including its cut, clarity, color, and carat weight, ensuring you receive a gemstone of unparalleled value and authenticity. We believe in transparency, and our certified lab-grown diamonds are a testament to that commitment.

Moissanite Authenticity

At London Diamond Exchange, we pride ourselves on offering only the finest quality Moissanite stones. Each Moissanite we sell comes with a Card of Authenticity, meticulously crafted to guarantee that every stone has undergone rigorous inspection and has been verified for authenticity and quality using industry-standard testing methods. Our Moissanite stones are not only renowned for their exceptional brilliance but also for their durability, matching that of high-quality natural diamonds. This card is our promise to you that your Moissanite is of the superior quality we are known for, providing you with both beauty and peace of mind.

Natural Diamonds

At London Diamond Exchange, our commitment to quality and ethical practices guides every decision we make. We previously offered natural diamonds, which were accompanied by either a GIA Certificate or an IGI Certificate, ensuring their authenticity and exceptional quality. However, due to our unwavering dedication to sustainability and ethical sourcing, we have made the decision to no longer offer natural diamonds.

Instead, we focus on providing lab-grown diamonds and Moissanite, which offer the same timeless elegance and brilliance as natural diamonds, while aligning with our values of environmental responsibility and ethical integrity. Our lab-grown diamonds and Moissanite stones are rigorously inspected and come with industry-standard certifications, guaranteeing that you receive only the finest quality. We believe these modern alternatives provide an outstanding choice for those who value both beauty and ethical considerations.
