Answer:
yes, gold can be created from other elements. The process requires nuclear reactions and is so expensive that currently it would cost a lot more than the price of natural gold available, therefore, unprofitable. Gold is the chemical element with 79 protons in each atomic nucleus. Every atom containing 79 protons is a gold atom, and all gold atoms behave the same chemically. In principle, gold can be created by simply assembling 79 protons, (and enough neutrons to make the nucleus stable).
Those are very fragile. It also depends on how bad of injury. There are tiny little bone that are sometimes hard to see.
