It does not rust or tarnish because gold will not chemically combine with any substances in the air
pure silver rings stay shiny because silver does not act with oxygen :)
which material does not loses its shine. Is gold
Oxidation of the metal
Most metals lose their luster when they are exposed to water because they react with the oxygen in the water and oxidize. An example is iron that reacts with the water to produce iron oxide, or rust.
Metals are likely to make anions. So they lose electrons to get a positive charge. The other elements gain electrons and get negatively charged.

No, gold does not tarnish. It is because acids and other gases have no effect on it. It does not lose its shine. It is a least reactive metal.

because it does not lose its shine, because it is a very slow reactor to air, meaning it doesn't break down or rust like other metals. also because it is rare, so it means it is special and very expensive so you look expensive!

sliver tarnishes much worse than gold and requires a lot of upkeep and can lose its shine
Gold doesn't react to oxygen so it doesn't rust, and it is generally a very stable element, meaning it won't react with other elements naturally and lose its shine.
Most metals lose their shine as they react with gases in the atmosphere or in a liquid.. The surface layer may react to fom an oxide, hydrated oxides, sulfide, sulfates, carbonates. Generally ths process makes the surface dull and it may get pitted. The process is called corrosion when it is iron rusting and tarnishing when it is silver forming black silver sulfide or copper forming a mixture of greenish products, "patina" whose composition depends on the location.Some metals do not lose their shine. Common examples are gold and platinum which are used as jewellery. Aluminium still looks shiny but there is thin layer of aluminium oxide which prevents the reactive aluminium metal from corroding.

They lose electrons, not elements. These are metals. Group I metals (IA or alkali metals), Group 2 metals (IIA or alkaline earth metals), transition metals (groups 3 thru 12), and all other metals.
Use a piece of unglazed ceramic material. Rub the gold against it. Fool's gold will leave a black streak, and real gold will leave a golden streak. This ofcourse works for gold and you will lose a bit of gold in the process. There are other methods for other metals and stones.
