The Promise of Purity
Every diamond we carry comes with independent certification from IGI, GIA, or HRD. You know exactly what you are buying before you buy it.
Our Story
Diamante started as a family business. In 1990, Hussein Moussaoui founded Al Moussawi Jewelry in Lebanon. He built it on straightforward principles: honest work, quality materials, and pieces that actually meant something to the people buying them.
In 2011, we lost him. It was not easy to continue, but his values were clear enough that the family knew what he would have wanted. So we kept going.
By 2019, the brand had evolved and was renamed Diamante Jewelry. Same foundation, new identity.
In 2025, we relocated to Muscat, Oman, a step that felt right given where the business was heading and the opportunities the market offered.
Today, Diamante specializes in natural and lab-grown diamonds, all internationally certified. We take the certification and sourcing side seriously because we think customers deserve to know exactly what they are buying.
More than thirty years on from where it started, the business is still family-run and still guided by the same values Hussein built it on. That part has not changed.

Every diamond we carry comes with independent certification from IGI, GIA, or HRD. You know exactly what you are buying before you buy it.
Over three decades, the most consistent thing about Diamante has been the clients who come back. For an anniversary. For a child's engagement. For the next milestone. That trust is not taken lightly.
From stone selection to setting and finishing, every piece meets the same standard regardless of price point.
The GCC has one of the world's deepest gold and diamond cultures. Diamante respects that tradition while designing for the way people actually live and wear jewellery now.
Every diamond we carry is sourced through responsible channels and verified through international certification. What you wear should have nothing to hide.
The Elite Assurance Program, our upgrade policy, and our buy-back guarantee are all built on one idea: we want to still be serving you in ten years.
IGI, HRD Antwerp, and GIA are the three most recognized diamond grading authorities in the world. Every Diamante diamond carries one of these certifications and the documentation to prove it.
