The shapes of the rough diamond

Since diamond is a crystalline network of carbon atoms, the shape of the rough diamond in most cases follows known geometric rules.

The different colors of the rough diamond

The color of a diamond depends on the impurities present in its crystalline structure.

Diamonds can take on a wide range of colors, from light yellow to black, brown, green, pink and blue.

A blue diamond owes its color to the presence of boron atoms in its structure, while it is the presence of nitrogen that gives the yellow color to the diamond. Finally, the presence of captive graphite in the crystalline lattice gives the diamond a black color.

The different types of rough diamonds

Depending on the jewelry needs, rough diamond can be used in different shapes.

The diamond can be in amorphous, rough or polished cubic form or even in slice form.

How much does a rough diamond cost?

First of all it is important to understand that there are two types of rough diamonds.

Some rough diamonds are dull and yield nothing when cut, so their value is low and they are very convenient to use in their rough state in jewelry.

Count 50/100 euros per carat for diamonds like this.

Others are translucent and can be cut and then sold on the traditional diamond market. Although the operation may be interesting from an economic point of view, know that it is difficult to evaluate the quality of a rough diamond.

The experts who evaluate the quality of rough diamonds work on batches of diamonds and any errors are compensated for on the number of diamonds evaluated as cut.

The price of these diamonds varies from 300 to 5000 dollars per carat. You can discover these rough diamonds on this page or even on this one.

Some rough diamonds can be purchased for as little as $10,000.
