Gold doesn't rust because the chemical corrosion doesn't affect gold... only iron-related metals or compounds. Gold is also a chemically unresponsive metal and doesn't really go through a reaction which would result in rusting... Gold won't rust in oxygen either...
With the exception of iron , no metals rust. Rust is the oxide of iron. However, most metals do form oxides. Notably Gold and Platinum do not readily form oxides.
Metals such as gold, platinum, and silver do not rust because they are inert and do not react with oxygen in the air to form oxides. Additionally, metals like stainless steel contain chromium, which forms a protective oxide layer that prevents rusting.
The gas that forms rust with water and iron is oxygen. Rust is formed when iron reacts with oxygen and water in a process called oxidation.
rust oxidizes when exposed to water
Rust is not toxic but it is disagreeable.
In "9k medium," the "9k" refers to a gold purity level of 9 karats. This means that the gold content is 37.5% pure gold, with the rest being made up of other metals to strengthen and color the gold.
To clean 9k gold, mix warm water with a few drops of mild dish soap. Soak the gold jewelry in the solution for a few minutes, then gently scrub with a soft brush or cloth. Rinse the jewelry with clean water and pat dry with a soft cloth. Avoid using harsh chemicals or abrasive cleaners on 9k gold.
Better to lose a 9k gold ring than a 18k one ! 18k is purer gold than 9k.
In United States Of Amirica Don't has value 9k of alloys soft gold !
No cause gold doesn't rust at al!!!
no such thing
10K is the minimum US standard and is 41.6% gold with other base metal. 9K is available in Europe and contains 37.5 % gold.
9K gold is approximately 37.5% pure gold, with the remaining 62.5% consisting of other metals like silver, copper, and zinc. This lower gold content makes 9K gold more durable but less valuable compared to higher karat gold.

No. 24k is 'pure' gold.
As of August 4, 2014 the price for one gram of 9k gold is 15.53. The prices of gold do change often due to demand and the economy.
9k is different from 18k or 24k because 24k is pure gold and 18k and 9k have more metals in them so that helps the become more endurable. but if you want pure metal get 24k
