Product Overview
- ZKZ Jewelry’s lab-created blue diamonds are synthetic (CVD/HPHT) round brilliant stones produced in Shenzhen with NGTC certification. They are offered in sizes from 0.03–3.00 ct (custom sizes available), supplied individually (MOQ 1 pc) with monthly capacity up to 10,000 cts and typical delivery of 3–14 days.
Product Features
- True carbon diamonds with identical physical and chemical properties to natural stones: round brilliant cut, excellent/very good cut, EX polish and symmetry, typically no fluorescence. Clarity ranges from about SI1 up to VVS1, blue color saturation, and polished finish; stones are supplied loose or set and come in plastic cases.
Product Value
- Provide the visual and material parity of natural blue diamonds at a fraction of the cost (typically 20–30% of natural diamond pricing), enabling large economic savings. They are conflict-free, more environmentally friendly (no mining), and support scalable, predictable supply for designers, retailers and manufacturers.
Product Advantages
- Vertical in-house production and full supply-chain control deliver stable quality, competitive pricing and rapid turnaround. Additional benefits include NGTC certification, lifetime manufacturing-warranty coverage, OEM/customization services, and broad stock availability for both CVD and HPHT types.
Application Scenarios
- Ideal for fine jewelry production (engagement rings, earrings, necklaces, pendants), bespoke and OEM collections, wholesale distribution to retailers, and designers seeking ethical/affordable blue diamonds. Suited for both single-stone luxury pieces and volume jewelry manufacturing.
