If you know about the elements and the electron orbit shells. Then the number of electrons in the outer most shell have preferred relationships in fitting together.This process is much more complicated when crystals are made of molecules in an array and the conditions of temp, electric-field, magnetic-flux, gravity, time etc etc during xtal formation... It is an extremely fascinating field of study and greatly useful in doping ( protuberances of tiny percentages of other atoms ) into elemental substances for the electronic crystal behavior of Semi-Conductors like Germanium and Silicon in the periodic chart...

Crystals have different shapes because of the elements in their molecule and how the molecules stack to make a crystal. Google salt molecule, diamond molecule, or quartz molecule, and see the difference in the molecule shape and how the molecules fit together to make a crystal.
Nope!The companies shape them to make them look bigger and better, and then sell the dust to other companies that use them for cutting discs, drill-bits, and things like that.Something like that...
suggested Google terms: atomic crystal structure shape. Maybe add : sugar, salt, quartz, fools gold. - Toga_Dan

They don't ;)A raw diamond looks quite ugly compared to the finnished product. - Downunder35m
Ummm... Hi Julien, I'd like to do your presentation about crystallization, because I think...Google your question. Is it that hard? There should be a checkmark that you have to click before publishing a question: "Did you check to see Google doesn't have your answer?". It might work a bit against the site, but that would be great... - Yonatan24
You are asking in the wrong spot, you should talk to my good old friend Google. - Downunder35m
