How to Identify Natural Rough Diamonds In The Right Way


Industrial grade and Gem quality diamonds are the two classes of rough diamonds that you end to come across in the market. Out of these the Industrial diamonds aren’t a good match for the common jewelry, rather they’re very effective for the industrial applications.

How tough is it to identify rough diamonds?

The octahedron has some traits that are present in all rough diamonds, although they may appear in various forms.

Grains & faces of the rough diamond

A rough diamond often bears a few triangular and naturally flat shapes known as the Octahedral faces. The presence of Trigons in these smooth faces is among their specific traits. Then you also have some natural grain lines present with the octahedral faces. A diamond that attains a perfect shape has 12 such grains along with 8 faces.

The presence of grain has widely been perceived in rough diamonds of multiple shapes. Dodecahedral faces or defined grains present in an Octahedron are of 12 different types. The grain lines are also easily identifiable due to heir wide range of markings. That fact that they are so easily distinguishable seems to be beneficial for you. The seams or grain lines are easily recognizable even in some of the diamonds that fall into the category of rough diamonds due to the smoothness of their texture. The dodecahedral faces of these diamonds are also among their most notable features.

You can further identify a rough diamond by its Trigons

Trigons don’t appear with all diamonds, but due to their characteristics, it’s much easier to distinguish them. The bases of Trigons sit closer to each other and at times they don’t even get segregated by any natural line. For instance, the triangular shape of Macle helps you identify them separately among other twin diamonds.

Ascertaining the true worth of these rough diamonds is often tough. Check out a few factors that are often taken into account while determining the value of rough diamonds.


Color isn’t the right factor for judging the true worth of a rough diamond. Only a few of them will fit into the category of perfect diamonds. The roughness of their outer layers often contributes towards their discoloration.


You may come across flaws in most diamonds. However, you shouldn’t consider judging the rough diamonds in terms of their clarity. A rough diamond buyer should be able to read the signs of warning when a flawless rough diamond is offered to him at negotiable prices.

Thermal Conductivity

A low phonon distribution and a powerful covalent bonding have turned diamonds into great heat conductors, unlike other electrical insulators. In natural diamonds, the thermal conductivity has been measured to be worth 5 times that of copper. A diamond is known to be heated up very fast. However, it’s really quite tough to destroy diamonds even when they conduct such high degrees of heat.
