Milla Exports works with all major international gemmological laboratories operating in China: GIA (Gemmological Institute of America), IGI (International Gemmological Institute), and NGTC (National Gemstone Testing Centre), as well as HRD Antwerp and other certifying bodies upon request. Each certification includes comprehensive grading reports detailing the four Cs: cut, colour, clarity, and carat weight, along with additional characteristics such as fluorescence, symmetry, and polish.

All our certified loose diamonds come with authentic documentation that can be independently verified through the issuing laboratory's database. Given our Chinese operations, we have particularly efficient access to GIA and IGI certification services with fast turnaround times, as well as NGTC certification which is highly regarded in Asian markets and offers competitive pricing.

Absolutely. Milla Exports maintains comprehensive inventories to meet diverse business requirements across all diamond categories. We supply natural diamonds sourced from international mining operations and processed through Chinese cutting and polishing facilities that combine traditional craftsmanship with advanced technology. We also offer lab-grown diamonds produced by leading Chinese manufacturers using state-of-the-art CVD and HPHT technologies.

China produces more lab-grown diamonds than any other country, creating exceptional quality and pricing advantages for buyers. Additionally, we provide conflict-free diamonds ethically sourced through Kimberley Process certified supply chains. We stock diamonds across all categories with appropriate certification clearly distinguishing natural from laboratory-created stones.

Milla Exports accommodates both large-scale jewellery manufacturers and smaller businesses in China's wholesale diamond market. While we excel at serving companies requiring significant diamond volumes for production operations—which is where China's scale advantages truly shine—we also assist clients who need smaller quantities of specific certified stones or specialty diamonds.

Minimum order requirements vary depending on diamond type (natural versus lab-grown), quality grade, certification level, and whether you're also utilizing our jewellery manufacturing coordination services. Our experienced team provides personalized quotations based on your specific needs, whether you're purchasing individual certified stones, bulk parcels for inventory, or diamonds integrated with manufacturing services.

Yes, absolutely. Milla Exports is firmly committed to ethical diamond trading practices and responsible sourcing. We source only conflict-free diamonds that comply with the Kimberley Process Certification Scheme, which China participates in and enforces through customs controls.
