Fancy Color Diamonds

Full-color colored diamond matrix, unlocking carat freedom and color imagination.


In the world of diamonds
Color is an eternal poem
Carat is a medal of freedom



High Light has successfully growning six color diamonds: red, orange, yellow, pink, blue and green, with the purity of their hues comparable to those of natural minerals.

Let every colored diamond become a footnote to your unique story.








Our colored diamonds range from 1-18ct, with clarity up to VVS-VS level, and a variety of cutting shapes can be customized.
All colored diamonds are equipped with certificates such as IGI, GIA, NGTC, etc. The carat, hue, and clarity data are traceable to ensure their value.

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
