Diamond Or cone * * * * * Partly correct. A rhombus can be called a diamond or a parallelogram or a quadrilateral. However, a rhombus is a 2-dimensional figure whereas a cone is 3-dimensional so you certainly could not call a rhombus a cone.

A hexagon is a 2-dimensional shape. A "structure" implies a 3-dimensional shape but you have not specified whether it is a hexagonal pyramid, a hexagonal prism or some other shape that is [partly] based on a hexagon. Without that information it is not possible to give a more helpful answer.

The net of a 2 dimensional shape can be folded into a 3 dimensional shape
Diamond and Graphite are the two pure forms of carbon
That depends on where the forces will be coming from. If both structures are subjected to forces in 3 dimensions, then the 3 dimensional structure will be less apt to fall over or something. If by strength you mean not compressing, then the 2 dimensional structure might be better theoretically, though you couldn't really build a 2 dimensional structure.

Graphite is a form of carbon where the carbon atoms are arranged in a layered structure, giving it lubricating properties and electrical conductivity.

Diamond and graphite are both allotropes of carbon, with different structures and properties. Diamond has a tetrahedral crystal structure, making it the hardest known natural material, while graphite has a layered structure with weak forces between layers, giving it properties of being soft and slippery. This difference in structure leads to diamond being used in cutting tools and as gemstones, while graphite is used as a lubricant and in pencils.
Both graphite and diamonds are composed of carbon atoms but have different structures due to the arrangement of these atoms. Graphite has layers of carbon atoms arranged in a hexagonal pattern, allowing it to be soft and slippery, while diamonds have a rigid and tightly packed structure that makes them the hardest known material.
According to Galleries page on diamonds:"Crystal System is isometric; 4/m bar 3 2/m; Crystal Habits include isometric forms such as cubes and octahedrons, twinning is also seen."
