Uncut diamonds, also called raw or rough diamonds, are diamonds in their natural state, straight from the earth, without cutting them into shapes, facets and polishing them. Diamonds form from the high pressure and temperature deep underground over millions of years and uncut diamonds honour them in their naturally mined state.

Why are they called “uncut”?

The name simply refers to the fact that these stones haven’t been shaped or faceted by a jeweller. They retain their natural crystal form, often octahedral, cubic, or other irregular shapes. Each one is unique, which means no two uncut diamonds look exactly alike.

The natural beauty of uncut diamonds

While polished diamonds are admired for their sparkle and brilliance, uncut diamonds are celebrated for their raw charm. Their irregular shapes, cloudy inclusions, and natural tones give them an earthy, understated beauty. This natural finish has become increasingly sought after among those seeking authenticity and individuality in fine jewellery.

How are uncut diamonds formed?

All diamonds form deep beneath the Earth’s surface under extreme heat and pressure. Over millions of years, carbon atoms bond to create crystalline structures. They’re brought closer to the surface through volcanic eruptions and mined from kimberlite rock or alluvial deposits.

Where do uncut diamonds come from?

Most uncut diamonds come from major diamond-producing countries such as Botswana, South Africa, Russia, Canada, and Australia. After mining, they’re sorted into some destined for industrial use, while higher-quality stones are chosen for jewellery design.

The appeal of uncut diamond jewellery

Uncut diamonds are gaining popularity for several reasons:

  • They’re distinctly unique; every stone is different.

  • They offer a more affordable alternative to traditional diamonds.

  • They have a natural, earthy aesthetic that appeals to modern minimalists.

  • They’re often considered more eco-friendly because they require less processing. This makes them particularly popular in boho, vintage, and ethical jewellery collections.

What colours do uncut diamonds come in?

Uncut diamonds can appear in a range of hues from white and pale yellow to brown, grey or even pink. Because they’re unpolished, the colour often looks subtler or cloudier, adding to their raw charm.

Are uncut diamonds real diamonds?

Yes, they are. They’re 100% natural diamonds, just not faceted or polished. They have the same chemical composition (pure carbon) as any other diamond. The difference lies in their finish and overall appearance.

How much are uncut diamonds worth?

Uncut diamonds are generally less expensive than polished ones because they haven’t undergone cutting and finishing. Their price is typically based on the potential worth of the polished diamond they could produce. Gem experts assess this using the same Four Cs that apply to cut diamonds: Carat (weight), Colour, Clarity, and the estimated quality of the Cut that can be achieved.

Can you cut an uncut diamond later?

Yes, a skilled gem cutter can later shape and polish an uncut diamond, though this may reduce its size. Many people, however, prefer to keep it in its natural state for its uniqueness.

Why are uncut diamonds popular in Indian jewellery?

In Indian jewellery, uncut diamonds, often called “Polki” diamonds, have been cherished for centuries. They’re a key element in traditional bridal jewellery, known for their regal and antique look. Polki jewellery is still widely worn in weddings and cultural celebrations.

How to style uncut diamond jewellery

Uncut diamonds look stunning in:

  • Vintage settings with yellow or rose gold.

  • Minimalist designs for modern wearers.

  • Stackable rings that mix polished and unpolished stones.

  • Statement pieces paired with textured metals or coloured gemstones.
    Their versatility makes them ideal for both everyday wear and special occasions.
