What Do Uncut Diamonds Look Like?

Uncut diamonds, also known as rough diamonds, are natural gemstones that have not yet been shaped or polished. Unlike the sparkling diamonds we commonly see in jewelry, uncut diamonds have a more raw and unrefined appearance. In this article, we will explore the characteristics and visual aspects of uncut diamonds.

1. Formation and Structure

Uncut diamonds are formed deep within the Earth's mantle, under immense heat and pressure. Over millions of years, carbon atoms arrange themselves into a crystal lattice structure, creating a diamond. This process results in a variety of shapes, sizes, and qualities.

When uncut diamonds are extracted from the Earth, they often have a rough, irregular shape. Their outer surface is typically covered in a layer of rough skin, known as diamond skin, which can be yellowish, brownish, or grayish in color.

2. Natural Colors

Uncut diamonds come in various natural colors, including white, yellow, brown, and even rare hues like blue, green, and pink. The color of a rough diamond is influenced by impurities or structural defects present within the crystal lattice. For instance, the presence of nitrogen can cause a yellowish tint, while boron can give a blue coloration.

It's worth noting that the majority of uncut diamonds are not colorless like their polished counterparts. Instead, they exhibit a wide range of hues, often with a cloudy or opaque appearance.

3. Transparency and Clarity

Uncut diamonds are generally not transparent like cut diamonds. Instead, they have varying degrees of transparency and clarity. Some rough diamonds may have internal inclusions or imperfections, known as birthmarks, which can affect their overall appearance and value.

These birthmarks can be in the form of cracks, fractures, or other mineral inclusions. However, the presence of birthmarks does not necessarily make the diamond less valuable, as it can add uniqueness and character to the gemstone.

4. Shape and Size

Uncut diamonds can come in a variety of shapes, depending on how they were naturally formed. Common shapes include octahedron, dodecahedron, and cuboid. Some rough diamonds may exhibit more complex shapes or irregular formations.

Regarding size, uncut diamonds can range from small crystals to larger stones weighing several carats. The size of a rough diamond is often a significant factor in determining its value and potential for cutting into a polished gem.

5. Surface Texture

The surface texture of uncut diamonds is generally rough and unpolished. The diamond skin mentioned earlier gives the stone a textured appearance. Additionally, the outer surface may have natural etchings, indentations, or irregularities caused by the diamond's journey through the Earth's crust.

These surface features can add character to the rough diamond, making each stone unique. However, during the cutting and polishing process, the surface texture is carefully removed to reveal the diamond's brilliance and sparkle.


Uncut diamonds possess a distinct beauty that sets them apart from their polished counterparts. Their natural colors, irregular shapes, varying transparency and clarity, and unique surface textures make them fascinating gemstones. While uncut diamonds may not have the same immediate allure as their polished counterparts, they hold immense potential and value, awaiting the skilled hands of gem cutters to unleash their true brilliance.
