can you mention one of its mechanical features?
Compressive strength.
Diamond cubic
The compressive strength and hardness of diamond and various other materials, such as boron nitride, is attributed to the diamond cubic structure.
we know that diamonds did not form from coal because UNANSWERABLE can you state any of its properties? Yes -  It is the hardest and least compressible. It has the highest thermal conductivity and the highest sound velocity. It has low adhesion and friction, and its coefficient of thermal expansion is extremely low. Its optical transparency extends from the far infrared to the deep ultraviolet and it has high optical dispersion. It also has high electrical resistance. It is chemically inert, not reacting with most corrosive substances, and has excellent biological compatibility. when was it discovered? Diamonds are thought to have been first recognized many centuries ago 3,000years but most likely 6,000years how is it used politically? UNANSWERABLE what is its status in space? They are very common in space. is there any carbon content in it? Yes - Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. what is meant by the term you mentioned in the last? The diamond cubic crystal structure is a repeating pattern of 8 atoms that certain materials may adopt as they solidify.

Diamond cubic [SEP] Mechanical properties
The compressive strength and hardness of diamond and various other materials, such as boron nitride, is attributed to the diamond cubic structure. Similarly truss systems that follow the diamond cubic geometry have a high capacity to withstand compression, by minimizing the unbraced length of individual struts. The diamond cubic geometry has also been considered for the purpose of providing structural rigidity though structures composed of skeletal triangles, such as the octet truss, have been found to be more effective for this purpose.
