Wholesale Loose Lab-Grown Diamonds

Wholesale loose lab-grown diamonds should be sourced against a commercial specification, not only a broad request for size and price. NUVU supports single center stones, matched pairs, calibrated requirements, accent-stone programs, fancy shapes, parcels, bulk orders, certified stones, and non-certified production stones for jewelers, retailers, designers, and production buyers.

The applicable quantity, availability, price, report option, matching requirement, timing, and delivery terms depend on the actual stone brief. Buyers can compare the wider wholesale lab-grown diamond supply paths or send a complete specification directly for review.

Suitable for one-off center-stone requests, sample sourcing, matched pairs, calibrated production needs, repeat inventory, parcels, and bulk purchasing.

Single Center Stones

Single center stones for engagement rings, custom pieces, or retail inventory can be discussed by shape, carat or measurements, color, clarity, cut or visual requirement, report preference, budget, and destination.

Matched Pairs

Matched pairs for earrings or balanced designs require more than two nominally similar grades. State the shape, dimensions, visual priorities, color and clarity range, report preference, quantity, and the acceptable matching direction.

Calibrated Stones

Calibrated requirements should identify target measurements, size distribution, quantity by size, allowable tolerance where known, color and clarity range, intended setting or production use, and whether repeat supply is expected.

Fancy Shapes

Common commercial shapes include round, oval, cushion, emerald, pear, princess, radiant, marquise, Asscher, and heart. Other available shapes can be discussed, but shape alone does not establish availability, matching, or price.

Parcel and Bulk Orders

Parcel and bulk requests should include the required size or carat distribution, quantity by specification, color and clarity range, certification requirement, matching or calibration needs, intended application, target budget or price where available, and destination.

Custom Requests

Custom stone briefs can be built from a specification sheet, production requirement, matched layout, jewelry design, or budget direction. NUVU reviews the known requirements and clarifies missing fields before quotation.

Build a Quote-Ready Diamond Specification

Shape and Intended Application

Confirm the shape and intended use: center stone, matched pair, side stone, calibrated production, accent program, parcel, or inventory. Round, oval, cushion, emerald, pear, princess, radiant, marquise, Asscher, heart, and other commercially available shapes can be discussed.

Carat, Measurements and Quantity

Provide carat weight or target measurements, acceptable range or tolerance where relevant, total quantity, and quantity by size or specification. A single center stone, matched pair, calibrated program, and mixed parcel require different availability and review.

Color, Clarity and Visual Direction

State the color and clarity range, cut or finish requirement where applicable, general visual priorities, and intended application. A grading label is useful, but the physical stone is also reviewed for appearance, condition, shape, proportion, and suitability for the order direction.

Certified and Non-Certified Supply

Certified and non-certified supply can be discussed according to use. Where an independent grading report is required, confirm the laboratory, report availability, report number, shape, carat, color, clarity, measurements, and other relevant information for the actual stone. NUVU is not an independent grading laboratory. Review the lab-grown diamond certification guide before confirming a report-dependent order.

Matching, Calibration and Tolerance

For pairs, calibrated stones, and multi-stone layouts, describe the required dimensions, quantity, visual balance, color and clarity relationship, and tolerance if already defined. Matching feasibility and any measurable tolerance are confirmed for the project rather than assumed from a generic category label.

How NUVU Reviews a Loose-Stone Requirement

Specification Review

The first review checks whether the brief identifies shape, size or carat, color, clarity, visual or cut direction, quantity, report preference, matching, calibration, intended use, budget, destination, and required date. Missing information is clarified before a useful quotation can be prepared.

Physical Review and Matching

Documentation is reviewed where it applies, but NUVU also reviews the physical stone. For pairs, calibrated requirements, or multi-stone projects, the review can include visual balance, condition, shape, proportion, measurements, and suitability for the intended jewelry or production direction.

Project-Specific Order Planning

MOQ is specification-based. Single center stones, samples, pairs, calibrated requirements, smaller projects, repeat programs, parcels, and bulk orders can follow different quantity and pricing logic. Availability, sample arrangements, matching, reports, and timing are confirmed in the quotation.

Documentation and Responsibility

The stone-to-order check compares the selected stone or parcel with the confirmed specification and intended application. Project-specific stone images, inspection photographs, videos, or other confirmation materials can be discussed when required, but they are not automatic deliverables for every order. See the diamond certification and quality control process.

NUVU manages buyer requirement collection, specification review, stone selection support, documentation review, physical stone review, matching and calibration requirements, order confirmation, shipment preparation, and delivery coordination as applicable. NUVU does not claim that every operation is completed by one legal entity or workshop. Specialized production resources or supporting partners may be involved while NUVU coordinates the confirmed order direction and reviews consistency.

From Stone Brief to Delivery

1. Send the Stone Brief

Send shape, carat or measurements, color, clarity, cut or visual requirement, quantity, certified or non-certified preference, preferred laboratory where required, matching or calibration needs, intended application, budget, destination, and target date.

2. Review Sourcing Options

NUVU reviews the specification and current sourcing direction, then identifies whether the request is best handled as a center stone, pair, calibrated program, parcel, sample, repeat requirement, or other project-specific supply path.

3. Confirm the Selected Direction

Before payment, confirm the selected stone or range, quantity, matching or tolerance direction, grading report details where applicable, price, quote scope, timing basis, payment stages, packing, shipping, customs and tax responsibility, insurance, and issue-handling terms.

4. Complete the Stone-to-Order Check

The selected stones are checked against the order direction. Review can include documentation, report number where applicable, general appearance, condition, shape, proportion, measurements, pair or parcel balance, labels, and preparation for the intended use.

5. Confirm Packing and Delivery

Packing, freight, destination, customs responsibility, import taxes, insurance, applicable delivery term, and worldwide door-to-door delivery arrangements are confirmed for the actual order and destination.

Wholesale Loose Diamond FAQ

Do you supply both certified and non-certified lab-grown diamonds?

Yes. Certified stones are relevant when an independent grading report is required for a center stone or retail application. Non-certified stones can also suit production programs, smaller stones, calibrated requirements, or manufacturing use. Report availability and the applicable laboratory must be confirmed for the actual stone.

Yes. Send the shape, target measurements, color and clarity range, quantity, intended use, and the visual or measurable matching priorities. NUVU reviews pairs, calibrated stones, and multi-stone requirements according to the project; no universal tolerance is assumed.

Samples and smaller project-based requests can be discussed. Sample price, shipping, estimated timing, source option, and any later order credit are confirmed individually. MOQ depends on specification, quantity, availability, certification, matching, calibration, and intended use.

Provide shape, carat or measurements, color, clarity, cut or visual direction, quantity, report preference and preferred laboratory where required, matching or tolerance needs, intended application, budget, destination, and target date. Use the loose diamond quotation form to send the known details.
