About ZKZ Jewelry
Nestled in Shenzhen's Shuibei district, the jewelry capital of China, a modern diamond dream factory is rewriting the narrative of fine jewelry. ZKZ Jewelry, a pioneer with over a decade of expertise in lab-grown diamonds, blends cutting-edge innovation with master craftsmanship to create a brilliant new chapter in China's intelligent manufacturing story.
Step into ZKZ's diamond universe, and you'll discover more than just a high-tech laboratory—this is a sanctuary of artistic creation. In 2015, our R&D team shattered technological barriers to cultivate the first Sakura Pink Diamond™, its delicate cherry-blossom hue instantly captivating the jewelry world. The subsequent debut of our Baby Pink Diamond™, with its soft, luminous glow reminiscent of a newborn's complexion, has since become a muse for top international jewelry designers.
At the heart of our operation lies proprietary CVD/HPHT hybrid cultivation technology, replicating the extreme pressure and temperature conditions deep within the Earth's crust. Each diamond undergoes a meticulous 120-hour growth process, precision-cut to 0.05-degree angles, and hand-polished through eight exacting stages—a testament to our relentless pursuit of perfection. This devotion has earned us dual IGI and GCID certifications, along with the trust of premier luxury brands worldwide.
we remain committed to slow, thoughtful craftsmanship.
As champions of sustainability, our 100% clean-energy growth chambers ensure every ZKZ diamond sparkles with an eco-conscious brilliance. Currently partnering with 15 elite jewelry houses, we're redefining luxury supply chains—from rare fancy-color diamonds exceeding 5 carats to complete private-label solutions.
In an era chasing instant returns, we remain committed to slow, thoughtful craftsmanship. True luxury demands time; eternal beauty deserves patience. ZKZ Diamonds offers not just products, but a philosophy of sustainable opulence and a visionary approach to jewelry.
In 2025, we open our doors wider to new collaborations. On this journey to recreate nature's marvels through science, we invite like-minded partners to co-author the next diamond legend. For in our eyes, every diamond is an unfinished story—and you could be its next narrator.
