Heavy liquids are substances in liquid form that have a known specific gravity (SG) and are used as a means of quick seperation of stones with similar appearance. In general these liquids are highly toxic and precautions should be taken when used.

Basic

Heavy liquids are stored in dark, transparent bottles to prevent light from influencing their physical properties and should be stored closed with a stopper to prevent evaporation.

Warning

Before using heavy liquids it must be stressed that one should avoid all contact with the skin and that they are non-potable. Always use tweezers to insert the gemstones and when in contact with the skin, you should thouroughly wash. When in contact with eyes, you should rinse your eye with streaming water and contact your medical Dr. immediatly.

Always use heavy liquids in a well ventilated environment and they should be kept away from children and pets.
