Jean-Marie Albanese

Ingénieur Gadzart (ENSAM, Ecole Nationale Supérieure d’Arts et Métiers), diplômé de la Gem-A de Londres (Association Gemmologique de Grande-Bretagne) et du HRD de Anvers (Diamond High Council), gemmologue par choix, passionné d’art, émerveillé par les pierres et leurs couleurs, son métier consiste à chercher le meilleur en matière de pierres précieuses et fines.

Il fournit aux bijoutiers, aux artisans et aux particuliers passionnés, les pierres uniques qu’ils recherchent. Il assure également la logistique d’approvisionnement aux ateliers et maisons de joaillerie en matières de pierres de couleurs et de diamants.

“ I continue to travel in search of sapphires, spinels, garnets, aquamarines, emeralds and other tourmalines… which will adorn your jewelry.

I am looking for stones that can be part of my clients' creative process or renew it with original stone proposals. ”
