Natural Rough Diamonds

Raw diamonds are characterised by an irregular shape and unpolished finish. They often exhibit a rough exterior, and can easily be mixed with other types of gemstones. Take a closer look, and their distinctive crystal structure – usually an octahedron, cybic or dodecahedral – becomes visible. Specialist knowledge and equipment are generally required to confirm the authenticity of natural rough diamonds.

Yes. As is common with all diamonds, their value is defined by the 4cs – albeit with a few caveats.

Their carat weight (larger is generally more valuable), clarity (fewer flaws and inclusions are worth more) and color (the more saturated and pure the color the more expensive ) – as well as their shape (which defines how much will be retained if cut).

Both jewelers and collectors alike appreciate unfinished diamonds for their unique appeal and transformation potential.

Unequivocally. A rough diamond is a real diamond in its most natural form. Their composition is identical to the polished gems, but they have not yet been crafted into the dazzling precious stone typically associated with diamonds or diamond jewelry.

The main difference between a rough and a polished diamond is the finishing process. Natural rough diamonds are uncut and unpolished, retaining their raw, organic appearance. Polished diamonds, on the other hand, have been cut and refined to maximize their brilliance, sparkle and color.

Yes. In general, rough diamonds are considered more affordable. This is due to their unprocessed condition. They are in essence, a raw material, ready to be shaped into the illustrious state . During the crafting process, a stone may typically lose a significant portion of its weight.

A natural rough diamond refers to a diamond that has been formed naturally through geological processes and remains in its raw, untouched state, as it was mined. These diamonds have not been altered, polished, or shaped in any way.

An uncut diamond, on the other hand, specifically refers to a diamond that has not yet undergone cutting and polishing to create a finished gemstone. While all natural rough diamonds can be described as uncut, the term "uncut" emphasizes that the diamond is on its way to becoming a polished gem.

Like polished diamonds, rough diamonds are evaluated using the 4Cs: carat weight, clarity, color, and cut potential. However, since they are unprocessed, the shape and surface characteristics of a natural rough diamond also play an important role in determining its quality and value.

Yes, natural rough diamonds come in a range of colors, from classic white and clear to more rare hues like pink, yellow, and blue.

It is good to keep in mind that polishing diamonds come with a risk, and therefor should be done by experienced professionals in order to have the best possible output.
