To build a direct bridge between jewellery brands and lab-grown diamond manufacturers.
Metra Lab Diamond exists to rebuild how lab-grown diamonds are sourced, priced, and supplied - replacing opacity and intuition with systems, data, and long-term reliability. We believe the future of the diamond industry depends on transparency, consistency, and long-term partnerships - starting at the source.
About Us
With deep expertise across diamond cutting, polishing, and process engineering, we operate industrial-scale production facilities equipped with our own self-developed automation systems. By integrating modern manufacturing technology with disciplined craftsmanship, we deliver stable supply, consistent quality, and scalable capacity to professional jewellery brands — enabling them to source lab-grown diamonds efficiently and reliably from origin.
Transparency sits at the core of how we operate. Every diamond is evaluated using the same standards as mined diamonds, based on the Four Cs, and supported by verified grading data and third-party certification.
