What Are Diamonds: Rough vs. Polished
Diamonds present themselves in two different forms: rough, as they are discovered, and polished, as they are prepared for display. Here’s a simple description:
- Rough gems from the earth (rough diamonds): These diamonds come straight from the mine, in their natural, pure state. Their exterior may appear dull, like glass fragments or common rocks. They have the potential for sparkle hidden within. They are the product of Earth’s origin.
- Finished sparkle (polished diamonds): These diamonds have been expertly cut and shaped to optimize their light performance. They are carefully polished to achieve a smooth, reflective surface that maximizes sparkle. They display a dazzling beauty. They have a lustrous shine.
Rough diamonds are the diamonds that come from the earth, and polished diamonds are the dazzling, finished gems.

- Informed shopping (smart shopping): It enables you to distinguish between the classic sparkle of a polished diamond and the unique charm of a rough stone. It allows for informed choices based on your personal preferences and aesthetic. It allows you to make the optimal choice. It allows you to shop with knowledge.
- Personal selection (choosing what’s right): You gain information about the diverse properties of both types of diamonds. This knowledge facilitates the selection of a diamond that resonates with your personal style. It helps you make personalized decisions. It helps you find the diamond that suits you best.
Knowing the difference helps you choose the diamond that’s right for you.
What Is a Rough Diamond?
A rough diamond is a diamond in its natural state, not cut or polished. It looks dull and rough like a normal rock. But from the inside, it has the ability to sparkle. This is how diamonds are found in the earth.
1. Appearance: What rough diamonds look like in nature
Diamonds, when mined from the earth, bear little resemblance to the glittering gems stored in jewellery boxes. Their natural appearance is quite different. Here’s a closer look:
- Dull surface (not lustrous): They often look hazy, opaque, lacking the clarity of polished diamonds. Their surface is usually uneven, with bumps and irregularities. They have a rough texture to the touch.
- Rock-like appearance (looks like a rock): Many rough diamonds look no different from ordinary rocks. They have no special sparkle or shine.
- Hidden sparkle (shine inside): Despite their ordinary outer appearance, they have the potential for remarkable sparkle. They need careful cutting and polishing to reveal their inner sparkle. They have a hidden sparkle.
Diamonds in their natural form look like rocks, but they have the potential to become beautiful, sparkling gems.
2. Formation and Origin: How Rough Diamonds Are Formed
Rough diamonds are produced far below the Earth’s surface, where they are subjected to extreme conditions. Here are the details of their formation:
- Rapid formation (inside the Earth): They are formed in the Earth’s mantle, a zone of extreme heat. They are compressed by tremendous pressure. This process takes billions of years, which is proof of their age. They are born from extreme geological conditions.
- Volcanic ascents (volcano tours): Volcanic eruptions act as natural elevators, bringing them to the surface. This is how they become accessible to us. They travel from the deep interior of the Earth. They come from the center of the planet.
- Exceptional rarity (very rare): Their formation requires a unique combination of time and conditions. This rarity contributes to their high value. They are precious because they are difficult to obtain.
Rough diamonds are formed deep in the Earth, take billions of years and are brought to the surface by volcanoes. This is why they are so rare and valuable.
3. Uses of Rough Diamonds (Beyond Jewellery)
Many people associate diamonds with fine jewellery, but rough diamonds have remarkable industrial utility. Their exceptional hardness makes them indispensable in a variety of manufacturing processes. Here’s how they are used:
- Unmatched Hardness (Very Strong): Diamonds have the distinction of being the hardest naturally occurring substance. This inherent strength makes them ideal for demanding industrial applications. They can cut and drill almost any substance. They are exceptionally strong and versatile.
- Precision Machining (Cutting and Drilling): They are employed to cut and drill extremely hard metals. They are used to polish metal surfaces to achieve precise smoothness. They play a vital role in manufacturing processes within factories. They are essential for heavy-duty industrial work.
Rough diamonds are used for tough industrial work because they are incredibly strong.
What Is a Polished Diamond?
A polished diamond starts as a rough diamond and goes through cutting, polishing and grading. This makes it shiny and ready for jewellery. Its shape, clarity, colour and cut are checked to see how good it is.
1. The Polishing Process: From Rough to Sparkling
Turning a rough diamond into a polished gem requires the expertise of skilled craftsmen who use special tools and techniques. Here’s a closer look at the process:
- Special Tools (Special Tools): Diamond cutters use tools specifically designed to work with the hardest materials on Earth. They use polishing wheels and compounds to achieve a smooth, reflective surface. They have many special tools.
