A jeweler needs to determine the density of an irregularly shaped, antique gemstone to verify its authenticity. The jeweler has physical access to a high-precision digital balance, but the gemstone's complex geometry prevents direct geometric calculation of its volume.
Describe how the jeweler can accurately determine the density of the gemstone.
In your answer, you should describe the experimental steps and how to ensure the measurements are accurate.
