Discover the Different Types of Rough Diamonds and Their Unique Beauty

Rough diamonds come in a variety of shapes, sizes, and qualities. Here are some common types of rough diamonds based on their characteristics:

1. Octahedron

Octahedron diamonds are rough diamonds that naturally form in the shape of an octahedron, which is a double pyramid with eight triangular faces. They have a symmetrical and well-defined shape and are often used for cutting and polishing into faceted diamonds.

2. Macle

Macle diamonds are rough diamonds that have a triangular or diamond-shaped twin crystal structure. They often have a flattened or twinned appearance, and their natural shape makes them suitable for specific diamond cuts and shapes.

3. Cubic

Cubic diamonds, also known as cubes, are rough diamonds that form in a cubic crystal structure. They have a distinct square or rectangular shape and can be used for cutting and polishing into fancy-shaped diamonds.

4. Irregular Shapes

Rough diamonds can also come in irregular shapes and forms, often referred to as “boart” or “melee” diamonds. These diamonds have uneven or irregular shapes, and they are usually smaller in size. They may have lower clarity or other imperfections but can still be used in various applications such as industrial tools, grinding wheels, or diamond powders.

5. Crystal Aggregates

Crystal aggregates are rough diamonds that form as a cluster or group of smaller diamond crystals that are naturally fused together. They can have irregular or unusual shapes due to the way the individual crystals have grown and merged.

It’s important to note that the classification of rough diamonds goes beyond their physical shape. They are also categorized based on their quality characteristics, including color, clarity, carat weight, and the presence of any inclusions or flaws. These characteristics determine the value and potential use of the rough diamond in the diamond industry.
