Lab grown diamonds for trade
Custom shape lab grown diamond sourcing
Discuss lab grown diamond shapes and measurements for your jewellery design with Lumex. Share the specification your project needs so the team can review feasibility and confirm the proposed selection, quotation and order terms with you.
Start with the design specification
A shape name or carat weight alone may not describe the stone your setting needs. Share the outline and measurements, explain the jewellery use and identify the details that must stay consistent across the order. A drawing or reference can help the discussion; ask the team how to provide any supporting files.
- Shape or outline, with the required length, width and height in millimetres.
- Target carat weight or range, quantity of stones and any matching or parcel requirements.
- Colour, clarity, growth method and laboratory report preferences where relevant.
- Intended setting or style reference, acceptable measurement differences and any project dates to discuss.
From requirement to confirmed order
Share the requirement
Contact Lumex with the design details, dimensions and quantity. Existing trade buyers can use the Create Your Own Shape workspace to manage their account workflow.
Review feasibility and the proposal
Confirm whether the requirement can be supported, what specifications are proposed and which measurements or grading details need agreement. Discuss the quotation and any supporting information before proceeding.
Confirm the commercial terms
Agree the final specification, quantity, price, report requirements and fulfilment terms for the specific order. Confirm timing with the team before scheduling your jewellery production.
Check existing shapes and sized selections
Your design may suit an existing shape or available selection. Explore the diamond shapes guide, compare certified lab grown diamonds, or review matched pairs and calibrated diamonds before preparing a custom requirement.
Questions about custom shape sourcing
Can any outline or size be supplied?
Feasibility depends on the requirement and needs review. Share the design and measurements with Lumex and confirm the proposed specification before placing an order.
What are the minimum quantity, tolerances and delivery time?
Ask the team to confirm quantity requirements, acceptable measurement differences, pricing and timing for your particular project. These terms are agreed for the order rather than assumed from this page.
Will the stones have an independent laboratory report?
State your report requirement at the enquiry stage. Confirm report availability, the issuing laboratory and which stones it covers as part of the proposal.
