”
The standard round diamond shape, also known as the round brilliant cut shape, consists of three parts: Crown, Girdle and Pavilion, with a total of 57 or 58 facets. In addition, there are crown angles and pavilion angles. Crown Angle (Crown Angle, Crown Angle) refers to the angle between the main facet of the crown and the horizontal plane of the girdle. Pavilion Angle (Tingjiao, Pavilion Angle). Refers to the angle between the main facet of the pavilion and the horizontal plane of the girdle.
(1) Table Facet There is one regular octagonal facet on the crown.
(2) The crown main facet (also known as the crown main facet, kite face, Upper Main Facet) There are 8 quadrilateral facets in the crown.
(3) Star Facet (Star Facet, Star Facet) There are 8 triangular facets between the crown main facet and the table.
(4) Upper Girdle Facet: There are 16 triangular-like facets between the girdle and the crown main facet.
(5) Pavilion Main Facet (Pavilion Main Facet, Pavilion Main Facet) There are 8 pavilion quadrilateral facets in total.
(6) Lower Girdle Facet: There are 16 triangular-like facets between the girdle and the main facet of the pavilion.
(7) The intersection of the main facets of the culet (bottom facet, culet) pavilion, which is point-shaped or octagonal small facets, with 1 or none (diamond weight greater than 1ct, all have bottom facets) .
Optimal brilliance is the goal pursued by modern diamond cutting. The factors affecting the brightness of diamonds are, on the one hand, the physical properties of the diamond itself, such as high refractive index, high dispersion, high hardness, etc.; another important factor is the cut of the diamond. Cut is a measure and observation that grades the perfection of a diamond's workmanship in terms of ratio and finish.

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

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 single crystal and polycrystalline CVD diamond lies not in equipment, but in growth logic. Single crystal 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
