About Maitri Diamonds
Founded in 2012, Maitri Diamonds was built on a simple but powerful belief: diamonds should be stunning, accessible, and entirely ethical. What began as a vision to create a modern alternative to mined stones has grown into a global lab-grown diamond manufacturer trusted by jewellers worldwide. The main difference is origin: natural diamonds form beneath the earth over millions of years, while lab created diamonds are created in a lab using CVD or HPHT in a matter of weeks. That means lab diamonds have the same chemical, physical and optical properties as natural diamonds, making them real diamonds with proven authenticity and the same optical performance.
Our mission is to revolutionise the fine jewellery industry with conflict-free, sustainable wholesale lab created diamonds, crafted using advanced technology and responsible practices. This modern alternative today can cost 20–40% less than mined stones, helping buyers stay within budget without exceeding spend while maintaining exceptional quality. Each stone reflects our commitment to innovation, precision cutting, and reduced environmental impact.
As we expand into the UK, our goal is to bring jewellers, designers and trade workshops a dependable, world-class supply partner, offering consistent quality and reliable supply.
Speak to Our Diamond ExpertIGI Certified Lab Grown Diamonds
All stones supplied by Maitri Diamonds can be provided with international certification from leading gemological laboratories, including the International Gemological Institute, IGI and GIA. Certification helps jewellers understand that stones are graded to the same standards as mined diamonds, using the 4Cs: Cut, Clarity, Colour and carat, ensuring transparency and confidence for UK jewellers sourcing diamonds for engagement rings, fine jewellery collections and bespoke commissions. Because lab-created and mined diamonds look alike, specialized testing is typically needed for identification, and the stone must be clearly disclosed as lab created, not mined.

Better Margins on Bulk Lab Grown Diamond Orders
For jewellers purchasing lab grown diamonds in volume, consistency across stones and pricing stability are critical. Because lab diamonds can be produced at scale, wholesale pricing is often more stable than mined supply. Maitri Diamonds supports bulk orders with structured sorting, matched specifications and repeatable supply, allowing your business to maintain uniformity across collections and ongoing production with confidence in every purchase.
We work with trade buyers to supply calibrated stones, matched pairs and grouped parcels based on exact requirements. Whether you are building stock for retail, fulfilling custom orders or scaling a product line, buying in bulk can reduce overhead and logistical costs for jewellery businesses, and these stones are typically sourced for production, retail turnover, or custom orders rather than resale-value preservation, as lab diamonds generally depreciate faster on resale than natural diamonds. Our bulk supply approach gives customers clarity, efficiency and consistency at every stage.
