Our Difference
Why Choose LuminaLab

Origin-Direct from Zhecheng
Located in China's premier lab-grown diamond hub, we source stones directly from our own facility -- cutting out middlemen and passing savings to you.
Every Stone Certified
All diamonds are graded and certified by IGI or GIA -- the world's most trusted gemological authorities. You receive full documentation with every purchase.
True Bespoke Design
Submit any sketch, reference, or concept. Our in-house designers produce 3D CAD renders for your approval before a single stone is set.
Global Shipping
We serve private clients, jewelry brands, and corporate buyers across 50+ countries. Secure insured shipping with full tracking included on every order.
Transparent Pricing
No hidden fees. Factory-direct costs mean you receive premium certified jewelry at a fraction of traditional retail prices -- without compromising quality.
Eco-Conscious Choice
Lab-grown diamonds are physically, chemically, and optically identical to mined diamonds -- with up to 85% lower carbon footprint. Beautiful and responsible.
How It Works
From Sketch to Masterpiece
Our end-to-end custom service transforms your vision into a certified lab-grown diamond jewel -- with complete transparency at every step.
01
Design Consultation
Share your inspiration, reference images, or hand-drawn sketches. Our design team works with you to define every detail -- shape, setting, metal, and carat weight.
02
Stone Selection & CAD Draft
We select certified lab-grown diamonds from our Zhecheng inventory -- graded for cut, colour, clarity, and carat. A 3D CAD rendering is shared for your approval before any work begins.
03
Expert Craftsmanship
Our master jewelers hand-craft the setting using your chosen metal -- 18k gold, platinum, or sterling silver. Every prong, pavé, and polish is executed to exacting standards.
04
Certified Delivery
Your finished piece ships with an official diamond grading certificate (IGI/GIA) and a quality assurance card. We serve private clients, jewelry brands, and corporate gift buyers worldwide.
