MT Gemological Laboratories is the first Saudi laboratory licensed and accredited by the Ministry of Commerce and the Saudi Standards, Metrology and Quality Organization (SASO) for examining diamonds, gemstones, and jewelry in the Kingdom of Saudi Arabia. We are also among the few laboratories worldwide to hold accreditation from a full member accreditation body of the International Laboratory Accreditation Cooperation (ILAC). Since 2015, we've been issuing certificates for diamonds, gemstones, and jewelry, adhering to the best and most renowned gemological examination standards. We've earned a strong reputation in the field due to our unwavering commitment to integrity and accuracy in everything we do.
Brand Story
The main concept behind the MT Gemological Laboratories brand mark is to portray the royal heritage of the laboratories through simple, minimalist symbols. Looking at the logo, we first notice the shield shape, which symbolizes security and the solid foundation of the laboratories. Moving upwards, the crown symbol represents heritage. A diamond positioned between two microscopes sits in the center of the shield, serving as the main symbol of the laboratories and representing the sector they operate within. At the bottom of the shield, two crossed keys symbolize knowledge and stability. As a significant part of the brand, two colors are used in the background: a deep, dark green and a gradient of golden shades. To maximize their potential, these were utilized with a pattern consisting of the crown symbol found at the top of the logo.
