PURPOSE: Provided is a method for coating jewel stones by forming a thin layer on the backside of the jewel stones using gold, platinum, tantalum, silver, silicon and the like in a form by which reflexibility is increased. CONSTITUTION: The method includes forming a thin layer of a metal on the backside of jewel stones using a sputtering apparatus at room temperature. The thin layer of a metal is made using at least one of chrome(Cr), copper(Cu), molybdenum(Mo), Iron(Fe), tantalum(Ta), titanium(Ti), aluminum(Al), gold(Au), lead(Pt), nickel(Ni), tin(Sn) and the like. The method further includes forming another thin layer of a metal on the metallic thin layer of the jewel stones. The thin layer is made using at least one of gold(Au), platinum(Pt), tantalum(Ta), silver(Ag), rhodium(Rh) and silicon(Si). The metallic thin layers are formed to a thickness of 1000 to 5000 angstrom.
