À propos

Global Mark Gemstones — la meilleure adresse de Dubaï pour les pierres précieuses certifiées — est un extracteur et tailleur de premier plan depuis 1980. Implantés à la source de l'une des régions gemmifères les plus prometteuses au monde, nous jouissons d'une position privilégiée pour sélectionner les meilleurs cristaux bruts dès leur sortie des mines.

Forts de près d'un demi-siècle d'expérience, d'un centre de taille intégré et de maîtres lapidaires, de liens étroits avec les propriétaires de mines d'Afrique de l'Est et d'une longue pratique de l'exploitation de gisements de pierres de couleur, nous offrons un service verticalement intégré, de la mine au client final.

Le parcours

De la mine jusqu'à vous

Cette gemme rare et magnifique a suivi un parcours unique à travers notre réseau en Afghanistan, aux Émirats arabes unis, en Inde et à Oman.

Nous retraçons ce parcours depuis l'entrée de la mine jusqu'aux confins du monde, là où la pierre trouve enfin les mains de son propriétaire.
