Diamond cutting refers to the art of cutting and polishing diamonds. The goal is to transform a rough diamond (uncut diamond) into a finished diamond with brilliance, fire, and high value. This process is extremely precise and requires a high degree of expertise, as diamond is one of the hardest natural materials on Earth, requiring specialized tools and methods to cut and polish it.
The main goal of diamond cutting
1. Improve the optical effects of diamonds: including brightness, fire and sparkle.
2. Maximize the value of the rough stone: During the cutting process, retain as much weight of the diamond as possible.
3. Create a specified shape: Diamonds are made into specific shapes (such as round, princess, pear, etc.) based on market demand.
Key technologies in diamond turning
1. Cutting ratio*,
- A diamond’s proportions are crucial to its optical quality; proportions that are too large or too small will affect its brilliance and fire.
2. Symmetry
- The symmetry of the facets directly affects the appearance and value of the diamond.
3. Polishing quality
- The smoothness of the polish affects the reflection of light, making the diamond appear brighter.
Common diamond cut shapes
Round Brilliant Cut
The most popular and classic cut, with 57 or 58 facets for optimal brilliance and fire.
Princess Cut
Square or rectangular cut, with a modern feel and fire second only to the round cut.
Emerald Cut
The rectangular step-cut emphasizes the transparency of the diamond.
Pear Cut
It combines the characteristics of circle and oval, and its shape resembles a water drop.
Heart Cut
Romantic heart-shaped design, relatively difficult.
The Importance of Diamond Cutting
The value of a diamond depends largely on the quality of its cut. Even a high-quality rough stone can significantly reduce its brilliance and market value if poorly cut. Conversely, an ordinary-quality rough stone can be transformed into something truly captivating through exquisite cutting. Therefore, diamond cutting is often called the art of "giving life to diamonds."
