01 / Materials & fit
Stone & Metal Specifications
Choose the stone origin first, then define the metal, dimensions and finish for each reference. These are inquiry routes; availability and final specifications need confirmation for your selected design.
01
Natural Diamond Jewelry
Build your buying brief around a clearly stated natural-diamond requirement and an agreed setting specification.
Stone
Specify natural or lab-grown origin, shape, dimensions, color, clarity and any grading-report requirements.
Material
Select the alloy and fineness for the design; confirm the available combination in the quotation.
Size & fit
Provide item dimensions, relevant size ranges and critical tolerances in the approved specification.
Plating
Specify surface finish and any plating material, color and thickness for review.
Pearl option
For pearl-and-diamond combinations, provide pearl type, dimensions and drilling details for a separate fit review.
Material selection across our business includes 9K, 10K, 14K and 18K gold and 925 sterling silver. Confirm the available alloy for each diamond jewelry reference before ordering.
02 / Written requirements
Diamond Grading Standards & Documentation
Agree a written specification for the selected stones and finished piece. No universal color, clarity or tolerance band is stated for all orders.
Record origin, shape, dimensions, requested carat weight, color, clarity and applicable cut information in the inquiry. Confirm the grading requirements for the selected stones and the reports needed for your destination.
Reports & traceability
If a particular grading report is required, identify the issuing laboratory and the stones to be covered. Confirm availability, scope, cost and timing for the selected order; a GIA, IGI or NGTC report is not included by default.
Setting, finish & tolerances
Define the measurements to check, setting requirements, finish reference and acceptable dimensional variation: agreed for the design and measurement method. Agree the inspection criteria before production.
As a diamond jewelry manufacturer, we develop products from buyer drawings, style references and specifications. OEM development follows your brief; the design responsibilities and scope of any ODM request require project review.
01
Prepare the brief
Share drawings or references, stone origin, alloy, dimensions, quantity and destination-market requirements.
02
Review the sample
Confirm sample method, charges and timing, then review the agreed dimensions, setting and finish before approving production.
03
Confirm production
Record approved specifications, inspection criteria, packaging and delivery terms in the order confirmation.
For trade buyers sourcing collections and custom projects. Confirm the following terms for each reference and quantity before placing your order.
Order quantities
List quantities by design, material and size. Confirm the applicable minimum and any mixed-style or custom-development conditions in the quotation.
Sampling & charges
Review the design and specifications, then agree the sample method, development work and charges. Any credit against production requires a separate written agreement.
Timing
Request separate sample and production schedules. Agree the required inputs and approval points, and plan production against the approved specification and quantity.
Individual protection, item identification, outer-carton method and any branded packaging: agreed for the order, including individual protection, labels and outer packing. Confirm your preferred packing list and labeling requirements.
Send quantities by reference, material and size. The quotation should state the applicable minimum, any mixed-style conditions and separate development charges.
Is there a sample fee?
The sample method is agreed after the design and specification review. Sample charges and development fees are quoted for the agreed work. Confirm any credit against a production order in writing before sampling.
What are the sample and production lead times?
Agree the sample review schedule and required approvals before work begins. Production timing depends on the approved design, material availability and quantity; allow separately for shipping.
Can you develop custom diamond jewelry from our design?
We develop products from buyer drawings, style references and specifications. Share the stone origin, alloy, dimensions and quantities for OEM review. The scope and design responsibilities of an ODM request require project confirmation.
Are diamond grading reports included?
Specify the issuing laboratory and which stones need individual reports. Before ordering, confirm availability, coverage, cost and timing; a GIA, IGI or NGTC report is not included by default.
