Lab-grown melee diamonds are small-sized diamonds produced using Lab diamond-growing technology. They share the same physical, chemical, and optical properties as natural diamonds.
With consistent quality, uniform cutting, and reliable supply, lab-grown melee diamonds have become an efficient and dependable choice in modern jewelry manufacturing.

Applications
Lab-created melee diamonds are widely used across various jewelry designs, including but not limited to:
l Ring shanks, pavé, and micro-setting designs
l Tennis necklaces and tennis bracelets
l Earrings, pendants, bands, and decorative settings
l High-end custom jewelry and large-scale commercial collections
Melee diamonds enhance the presence of a center stone while adding balanced and refined brilliance to the overall design.

Foshan Highlight Intelligent Technology Co., Ltd. has been deeply involved in the CVD-grown diamond field for many years. Leveraging its mature core technologies and differentiated process layout, it has achieved full-dimensional coverage of white diamond products. All of the company's white diamond products are pure carbon crystals with a hardness of 10. Their physical and chemical properties are completely consistent with natural white diamonds, placing them firmly in the category of genuine diamonds.
Significant core technological advantages: Relying on a stable and controllable cultivation environment, it can produce high-color diamonds ranging from D to F, with clarity generally reaching VS1 or higher standards. They are virtually flawless to the naked eye, and their fire and brilliance rival top-grade natural white diamonds.
Our product highlights: Standardized grading standards, transparent and controllable selection: Strictly adhering to the international diamond grading system, key parameters such as color (D-J), clarity (SI1-VVS1), cut (EX-VG), and carat weight are clearly marked. Products come with authoritative IGI testing certificates, supporting full traceability and verification.
Green and sustainable development, fulfilling social responsibility: The cultivation process requires no extraction of earth's crustal resources, avoiding the environmental damage caused by natural diamond mining from the source. It is a superior choice that combines aesthetic value with environmental protection.
High cost-performance advantage, breaking down market price barriers: Compared to natural white diamonds, our CVD white diamonds are significantly more competitive in price. Within the same budget, consumers can choose larger carat or higher quality products, helping them easily achieve “real diamond freedom.”

CVD Single-Crystal Diamonds: An Analysis of the Complete Processing Workflow from Gas-Phase Deposition to Finished Diamond Chips
MPCVD (Microwave Plasma Chemical Vapor Deposition) technology is currently the core process for producing high-quality single-crystal diamond s. Thanks to its advantages of low defect rates, high purity, and controllable large dimensions, it is widely used in fields such as semiconductor heat dissipation, precision optics, and high-end sensors. The final quality of single-crystal diamond s depends on comprehensive process control throughout the entire workflow—from vapor deposition growth to pos
Single-Crystal or Polycrystalline Diamond — Which Has Greater Potential?
As diamond continues to enter industries such as semiconductors, thermal management, optics, high-power electronics, and precision machining, the requirements for diamond materials are also evolving.
Diamond Polishing and Grinding Processes: Core Challenges and Industry Hurdles
Diamond is often hailed as the “ultimate material” – ranking 10 on the Mohs hardness scale, boasting an ultra‑high thermal conductivity (~2,200 W/(m·K)), excellent chemical stability, and broad optical transparency. These properties make it irreplaceable in cutting‑edge applications such as semiconductor heat dissipation, high‑end optics, and quantum chips. Yet the paradox of “good materials are hard to process” is nowhere more evident than in diamond. From rough grinding for planarization to at
Single-Crystal vs Polycrystalline CVD Diamond: Process Difference Lies in Growth Logic, Not Equipment
The process difference between singlecrystal and polycrystalline CVD diamond lies not in equipment, but in growth logic. Singlecrystal and polycrystalline CVD diamond are two functional new materials with completely independent growth mechanisms, lattice structures and performance systems. Their process logic, product features and application boundaries diverge fundamentally from the very start of deposition and growth. Comparing or selecting materials without considering their underlying crys
