Precision Lab-Grown Diamond Wholesale Supply

Elmonas provides precision-led lab-grown diamond wholesale supply for buyers who need exact specifications, coordinated stones, and a repeatable path from brief to delivery. It is designed for US and EU jewellers, manufacturers, designers, and wholesalers who need a direct technical conversation rather than an anonymous catalogue listing.

Key facts

• Certification: IGI is the standard route where applicable; other laboratories can be discussed when a buyer or channel requires them.
• Tolerance range: agreed in writing for each order before selection or production; calibrated work runs to a tolerance of plus or minus 0.05mm on diameter and length-width.
• MOQ: no minimum order for stones 2 carats and above; 10 carats total minimum when individual stones are below 2 carats.
• Lead time: 1 to 5 working days for ex-stock stones; 5 to 10 working days for bespoke and cut-to-order work; the production stages are confirmed with each order.
• Payment terms: flexible, agreed per order; advance, LC, or memo terms available depending on order size.
• Primary shapes: rounds, ovals, pears, marquises, emeralds, radiants, cushions, hearts, and agreed custom forms.

Marketplaces can provide breadth and speed; local wholesalers can help with urgent inspection; trade shows support supplier discovery. Direct manufacturer sourcing is most useful when the buyer needs calibrated layouts, matched pairs, exact custom cuts, or a repeat programme tied to a documented specification.[1]

The starting point is a clear brief. Include shape, measurements, colour and clarity range, quantity, cut requirements, setting constraints, treatment disclosure, certification preference, destination, and CAD or layout reference. Separating essential requirements from preferences makes the quote more useful and exposes feasibility questions early.

Precision, not volume, means focusing on the exact job: how stones must fit together, what the setter needs, which attributes must remain consistent, and what evidence is required for approval. CVD and HPHT can both be valid routes; the appropriate choice depends on the finished specification, not a universal claim that one method is always superior.

What you can check before you ask for a quote

The public stock list at /availability shows 12,209 certified lab-grown stones available to order, confirmed in your quotation. At the October 2026 snapshot, 99.7% of listed stones were IGI-certified, and the catalogue was deepest in fancy colours and in sizes above 2 carats: white D-G goods numbered 1,941 stones, elongated cushions 922, and step-cut shapes 1,701. Calibrated baguettes and matched layouts are cut-to-spec work, available to order and confirmed in your quotation; those requirements are quoted against production, not against a stock claim.

Every stone can be reconciled to its grading report before payment; the three-step check is described in how to verify an IGI lab-grown report. Your enquiry is handled by named people: Akshay Mungalpara and Rashesh Vadodariya, on WhatsApp or email, not an anonymous trade desk.
