Shaped
by Hand,
Perfected
in Every Facet
From rough stone to radiant jewellery — JNK DIAM brings precision craftsmanship and certified quality directly to B2B partners worldwide.
Manufacturers,
Not Middlemen
We operate strictly as manufacturers and direct suppliers. JNK DIAM supplies certified loose diamonds, finished diamond jewellery, and — on jewellery orders — both the set piece and the accompanying certified loose stones together.
Every diamond we supply — whether loose or set — carries internationally recognized GIA, IGI, or HRD certification, backed by full documentation and ethical provenance from source to delivery.
Loose Certified Diamonds
GIA, IGI & HRD certified loose diamonds supplied in any cut, carat, colour, and clarity — entirely as per your specification.
Finished Diamond Jewellery
In-house crafted diamond jewellery — rings, necklaces, earrings, bracelets — with certified diamonds set to your design.
Jewellery + Stones Together
Order jewellery and receive the finished piece along with certified loose diamonds — full traceability and documentation included.
Every Diamond,
Certified
Each stone is backed by internationally recognized laboratory certification — ensuring accuracy, authenticity, and global trade confidence for every B2B partner.
Grading Standards
Each certified diamond is assessed across the full 4C framework plus additional optical precision criteria used by all three labs.
Certification guarantees resale confidence, international trade acceptance, and transparent valuation — the foundation of every trusted B2B partnership.
