Coloured Lab-Grown Diamonds
This collection offers lab-grown diamonds in fancy colours including pink, blue, and yellow, produced using CVD (Chemical Vapour Deposition) technology. Colours are achieved through controlled growth conditions that permanently alter the diamond's crystal structure. Stones are available from 0.10 carat to 2.00+ carats in multiple shapes including round brilliant, oval, emerald, and princess cuts. It is designed for retailers, jewellery manufacturers, and traders requiring coloured diamonds for accent work, bespoke designs, and differentiated product lines. LabGems operates as an Antwerp-based wholesale supplier with direct production access and verified in-stock inventory.
Operational Advantages for Trade Buyers
Coloured lab-grown diamonds provide design differentiation and respond to growing demand for non-traditional engagement rings, statement pieces, and mixed-colour settings. Manufacturers can specify colours, shapes, and carat weights to create signature collections or fulfil custom commissions without relying on limited natural colour diamond availability. In-stock inventory across pink, blue, and yellow enables immediate allocation, while custom colour requests can be coordinated through production planning for specific project requirements. Dispatch occurs within one business day for verified payments on in-stock stones. For manufacturers creating mixed-stone designs, coloured diamonds can be paired with fancy shaped diamonds for complementary centre stones or combined with single round melee for halo or pave settings. Trade buyers can also coordinate coloured accent stones with 1ct melee parcels for consistent production runs.
Certification and Grading for Trade Evaluation
Each coloured diamond is supplied with documentation confirming lab-grown origin, colour grade, carat weight, clarity, and cut quality. Colour intensity and hue are assessed using gemological standards, allowing trade buyers to evaluate stones consistently and establish transparent pricing structures. While coloured diamonds follow modified grading criteria compared to white diamonds, documentation provides the necessary specifications for supply chain compliance and customer verification. Buyers can select colour intensities and clarities based on application requirements and target market positioning. For buyers requiring fully certified white centre stones, certified diamonds are available with comprehensive IGI documentation.
Designed for Market Differentiation and Margin Opportunities
Coloured lab-grown diamonds support margin expansion through product differentiation and reduced competition on commodity white diamonds. Trade buyers can develop exclusive colour-based collections, respond to trending hues, or offer customisation options that command premium positioning. The controlled production environment ensures colour consistency across multiple stone orders, allowing retailers to maintain signature styles and manufacturers to execute production runs with predictable specifications. Volume pricing is available for recurring colour orders. Buyers requiring certified white diamonds for traditional centre stones can source certified diamonds or coordinate coloured accent stones with white melee for mixed designs. For complementary materials beyond diamonds, lab-grown gemstones offer additional design possibilities.

Frequently Asked Questions (FAQs)
Lab-grown diamonds available in fancy colours such as blue, pink, yellow, green, orange, and other custom hues.

Yes. Custom colour requests may be available depending on production capacity, contact our team for options.
