Our Story
Built on Trust Since 1990
Founded in Lebanon in 1990, Diamante spent over three decades building its name on one principle: every diamond should come with complete trust. In 2025, the house brought that same standard to Muscat and to the families, couples, and clients of Oman and the GCC.
Every diamond we carry is independently certified by IGI, HRD, or GIA. Every purchase comes with our Elite Assurance Program. Every piece is made to last well beyond the moment it was chosen.
