At Ali Diamond, trust, transparency, and craftsmanship are at the core of everything we create. Every diamond piece is accompanied by a detailed certification, providing an independent overview of the authenticity and specifications of the diamonds used, including carat weight, clarity, colour, and cut. Certification is carried out by qualified gemologists and recognised laboratories, offering clients complete confidence that each piece is accurately represented and professionally assessed.

Ali Diamond Certification: Complimentary with every qualifying purchase and issued by our in-house gemologist. Each certificate includes detailed diamond specifications, stone shape(s), and the unique design reference of the piece.

Solitaire diamonds over 1 carat are accompanied by an internationally recognised laboratory certificate from either Gemological Institute of America (GIA), International Gemological Institute (IGI), or HRD Antwerp (HRD Antwerp), depending on the stone and availability.

Jewellery pieces featuring multiple diamonds with a combined total carat weight exceeding 1 carat are accompanied by an International Diamond Testing (IDT) jewellery certificate for the complete piece.
