Diamond Cleavage

Diamond Cleavage

   
This thick piece of cleavage could have been separated by the force of nature or in a cleaver's shop.

Diamond cleavage would not qualify as an exception to the rule since it is not a whole stone but rather a piece of a whole stone that has been divided from its original state. Due to the forces of nature, many times rough is split (cleaved) before it is discovered. The flat triangular pieces are discounted depending on their depth. Thicker pieces can be used to make triangular step cuts or trillions.

How to see a Macle diamond

The Macle

   
You can see where the two crystals meet in forming this macle.

The exception to the rule of every diamond containing twelve individual grains would be the macle. This would be like the Siamese twins of diamond rough. Two crystals have grown into one to form one whole. This would count as an irregular since the weight losses are generally greater. Cutting these can be an extremely arduous task due to conflicting grains where the crystals meet each other, so expect higher labor costs.
