What is a Rough Diamond?

A rough diamond is a diamond that hasn’t been cut, shaped, or polished. Freshly mined, these stones are natural and unrefined, revealing a rugged surface and varying shapes. Rough diamonds are composed of pure carbon, crystallised under immense heat and pressure over millions of years. Their appearance is distinct from the polished diamonds seen in jewellery stores, which are cut to maximise brilliance and symmetry.

Are Rough Diamonds Valuable?

Yes, rough diamonds are valuable. Their worth is determined by the same factors as cut diamonds: carat weight, colour, clarity, and, in the case of rough diamonds, sometimes shape. However, the value of a rough diamond is generally lower than that of a polished diamond of the same quality due to the labour involved in cutting and polishing. For those interested in bespoke jewellery, rough diamonds provide a unique and sometimes more affordable option without sacrificing authenticity.

Why Choose a Rough Diamond?

Opting for a rough diamond can be a meaningful choice. Since each rough diamond is unique, it allows for one-of-a-kind jewellery pieces that reflect a personal style. Additionally, they often carry a lower price tag than polished stones, making them an attractive option without compromising on quality or authenticity. Furthermore, the rise in ethical sourcing has brought attention to the provenance of rough diamonds, with buyers seeking stones that align with sustainable and ethical standards.

In Conclusion

Yes, rough diamonds are real diamonds. They may look different from the classic gemstones we know, but they’re just as authentic. These raw stones provide a distinctive look, capturing the essence of natural beauty and adding individuality to jewellery pieces.
