Answer:
Shine of gold ornaments decrease with time and they become dull because gold is a relatively soft metal, most jewelers mix it with other metals such as silver, copper and nickel to increase its hardness and durability.
Elements such as sulphur and chlorine react with the other metals in the gold jewelry, causing it to corrode and turn black, thus blackening the skin underneath.
