Diamond as one of the structures of Carbon, with high physical and mechanical properties which obtains as a mineral around volcanos during many centuries, have been using as an ornamental rather it would be used within industries such as stonecutting. Most popular diamondoids as most similar structures of Diamond are Adamantane, Diamantane, Triamantane that could be synthesized through acid and base solution. Natural synthesis of Diamond with lower weight than 1 carat and volume of 0.4-1(mmc) through nature could be as many years as a long process. But within this project, using graphite obtained by burnings of natural fibers to reach the graphene as a laminar structure of carbon and also recrystallization method as a template process like recrystallization of sugar hydrocarbons obtain to new carbon structures like diamondoids in a short process. Following the aim, during Hummer’s Method, first graphene within ice bath using sulfuric acid changed to graphene-oxide which has high reactivity due to oxygen bounded groups on carbon layers. The product as a paste has also high electrical conductivity, therefore it can be used to produce batteries. However, recrystallization of paste under microwaves within 300-30,000 (GHz) radiation through microwave or induction ovens can change configuration of laminar carbon to polygon structure and increase of volume. Note that, precautions like using gloves, safety glasses and mask are very important due to burning characteristic of sulfuric acid and etc.
