WHOLESALE LAB GROWN DIAMONDS
Wholesale lab-grown diamonds typically cost 70% to 90% less than mined diamonds, yet sourcing them reliably remains one of the biggest challenges for jewelry businesses. Inconsistent quality, opaque supply chains, and unpredictable inventory plague the wholesale diamond market.
Maitri eliminates those frustrations by manufacturing every stone in-house using Chemical Vapor Deposition technology, delivering certified lab grown diamonds with full traceability, competitive pricing, and global availability.
If you're a jeweler or retailer struggling with inconsistent diamond quality, limited inventory depth, or suppliers who can't verify where their stones actually come from, you're navigating a fast-moving and competitive market without the tools you need to succeed.
Most wholesale diamond channels rely on a web of middlemen, brokers, resellers, and trading desks, each adding markups, delays, and opacity. Maitri was built to solve exactly this. As a direct CVD technology manufacturer, we design, grow, and polish every diamond ourselves, so every stone comes with complete documentation from the diamond seed it began as, through the growing chamber, to the finished polished diamond in your display case.
We grow every diamond using Chemical Vapor Deposition, eliminating middleman markups and supply delays. No resellers. No brokers. You buy direct from the source.
Every stone ships with full documentation from seed to polished diamond, reducing the logistical complexities that plague traditional channels.
Our manufacturing process appeals to environmentally conscious retailers. Every stone is conflict-free, with no mining footprint and verified origins.
We maintain supply across all 4Cs grades, shapes, and sizes, from a 0.5-carat oval to a 4-carat emerald cut, with consistent availability.
Every wholesale diamond ships with independent grading reports covering the full 4Cs, essential for verifying quality in larger lab-grown diamonds.
Our controlled, in-house growing process means fewer rejections and more predictable inventory for your business.
Submit your business credentials for wholesale account verification. Once approved, you gain access to our digital catalog with real-time inventory, pricing, and specifications. The entire setup takes days, not weeks.

Every shipment includes secure packaging, full insurance, and international shipping documentation, with certification and traceability paperwork accompanying each diamond.
Most wholesale diamond suppliers are resellers, aggregating stones from multiple sources with inconsistent quality standards and zero transparency about growing methods. Maitri operates differently.
- Stones pass through brokers, resellers, and trading desks
- Inconsistent quality and certification practices between batches
- Little to no visibility into growing method or treatments
- Vague, unverifiable environmental claims
- Long backorders and unpredictable restock timing
- In-house CVD growing technology, with no middlemen
- Complete supply chain transparency, documented at every stage
- Every stone traced back to its specific growth chamber and seed
- Climate neutral manufacturing built on measurable processes
- Consistent global inventory across grades, shapes, and sizes

Our Emerging Retailer Program has accessible entry points designed for businesses just beginning their lab grown diamond inventory, and volume discounts increase at each tier. Contact our wholesale team via email for specific MOQ details tailored to your business.
How does CVD technology ensure consistent diamond quality?
Chemical Vapor Deposition creates diamonds in a precisely controlled environment. Carbon-containing gases are introduced into a vacuum chamber where plasma breaks them down, depositing carbon atoms layer by layer onto a diamond seed at approximately 900-1300°C. Temperature, pressure, gas composition, and growth duration are monitored continuously, and periodic cleaning cycles remove non-diamond carbon. After growth, every stone undergoes cutting, polishing, and quality inspection before certification, which is why lab-grown diamonds offer superior quality consistency compared to stones sourced from varied and unpredictable geological conditions.
What certifications come with wholesale diamond orders?
Every wholesale diamond ships with independent certification from IGI. Reports include identity confirmation (lab grown versus natural), growth method disclosure (CVD), the full 4Cs grading, treatment history, and laser inscription of the certificate number. Our traceability documentation covers the complete journey from seed to polished stone.
How quickly can custom diamond specifications be fulfilled?
Standard certified stones from existing inventory ship within days of order confirmation. Custom CVD growing requests, such as specific carat weights, colors, clarity grades, or shapes, typically require 3 to 6 weeks for growth, plus additional time for cutting, polishing, and certification. Larger stones or rare fancy colors may require extended timelines, and your account manager will provide precise lead times for each custom request.
