What would be a tool used for finely manipulating small gems?

Precision tweezers are essential tools for finely manipulating small gems due to their design and functionality. These tweezers feature a slender, pointed tip that allows for delicate handling without damaging the stones. Their ability to grasp and control small, often fragile gems is crucial in various tasks, such as setting stones into jewelry, arranging them for inspection, or during the cutting and polishing processes.

Other tools listed serve different purposes; for instance, saws are used for making larger cuts on rough stones or slabs, while hammers are typically employed for breaking or shaping rock rather than precise manipulation of small, polished gems. A scoop, while useful for picking up gems, does not provide the control needed for nuanced work or when handling delicate items, which is why precision tweezers are the most suitable choice for this task.
