Inside KIRA's lab grown diamond craftsmanship process

Welcome to KIRA, the world's largest lab grown diamond grower, where science meets artistry.

The seed-to-sparkle journey

Cultivating the seed

Everything starts with a seed, a tiny fragment of crystal that acts as the foundational building block of a diamond.

Growing in a controlled environment

Chemical vapour deposition (CVD) places the diamond seed in a chamber where carbon-rich gases are introduced and broken down, crystallising layer by layer.

Precision cutting and shaping

Our skilled artisans use advanced machinery to shape stones into round, pear, cushion and more, from 0.18 carats to over 10 carats. Every angle is polished carefully for optimal light return.

Certified quality

Every KIRA stone undergoes stringent checks to meet international standards, and ships IGI certified, with non-certified options available on request.

A planet-friendly approach

Our facility runs on solar power, cutting our carbon footprint significantly, and our process runs seed to jewellery under one roof.
