Real gold does not tarnish or turn black, as it is a highly stable and non-reactive metal. Gold is one of the least reactive chemical elements and is highly resistant to corrosion, rust, tarnish, or other chemical or environmental damage.
However, gold jewelry can appear to turn black or become discolored over time due to a buildup of dirt, oils, or other contaminants on the surface of the metal. This can give the appearance of tarnish or discoloration but is not an accurate indication that the gold is tarnished or damaged.
To keep your gold jewelry looking its best, it is recommended to clean it regularly with a soft cloth and mild soap and water or a specialized gold cleaner. Avoid exposing gold jewelry to harsh chemicals or abrasive materials, as these can cause damage or discoloration over time. With proper care and maintenance, gold jewelry can remain beautiful and lustrous for many years.
