DISCOVER THE ROUGH DIAMOND

The vast majority of diamonds found on our planet were formed much deeper in the earth’s interior than most other minerals, at depths of over 140 km and temperatures of 900 to 1400°C in the upper mantle. They were formed in deep rocks such as eclogite and peridotite, and were brought close to the earth’s surface by volcanic magma. Diamonds are not found in the rock in which they formed, but rather in the rock in which they were transported, namely Kimberlite and Lamproite.

All rough diamonds have ‘birthmarks’, or imperfections, that were created during the long natural formation process. There are many different types of inclusions and flaws. Here are some of the most common types:

Clouds: Internal inclusion that has a hazy, cloudy appearance. Often
caused by a cluster of pinpoint inclusions close together.

Crystals: The presence of small crystals or minerals often occurs naturally in diamonds.

Feathers: Internal inclusions caused by small cracks sometimes take on a feathery appearance.

Graining: Sometimes crystal inclusions form in a line that appears grainy. These lines make the polishing process more difficult as the diamond must always be cut against the grain.

Naturals: Flaws on the surface that were left untouched by the diamond cutter. These are often a sign of good cutting practice, as the diamond cutter has minimized the weight loss of the original rough diamond.

Blemishes: Blemishes appear on the diamond surface. They may occur naturally but are more often caused by external factors during the cutting process.

Scratches: These are fine lines on the diamond’s surface. They may occur naturally or may be a result of the cutting process.

Pits: Small indentations on the diamond surface may take on the appearance of pitting.

Nicks: Tiny chips of the diamond surface. Nicks can be removed during the cutting process by adding facets, however this may also reduce the diamond’s brilliance.

Each rough diamond is amazingly unique, featuring unique birthmarks, tiny variations, and wonderful imperfections.
The life experiences that create its personality.
