Lagani is an Auckland-based lab-grown diamond jewellery brand, founded to make premium diamond jewellery feel within reach without compromising on quality.

We trade online only, which keeps things simple, transparent, and fairly priced. By selling direct, we avoid unnecessary mark-ups and can focus on what matters: quality craftsmanship and beautiful diamonds.

Every piece is made with real lab-grown diamonds that have the same brilliance, hardness and durability as mined diamonds the only difference is how they’re formed.

We design and create timeless diamond jewellery made to be worn every day and treasured for years — from classic studs and tennis bracelets to custom engagement rings.

A Note From the Founder

My purpose for Lagani is to make premium lab diamond jewellery more accessible through honest pricing and uncompromising quality for people so it can be enjoyed by many, not just a few.

From your first message to your final piece, we guide you with care, no pressure, just clarity.

— Satish Kathiriya, Founder
