gold

Definition:

Gold is a yellow-colored high-quality metal that was used for making jewelry and religious objects. It was the most valuable metal in ancient times.

In Bible times, many different kinds of objects were made out of solid gold or were covered with a thin layer of gold.
These objects included ear rings and other jewelry, idols, altars, and other objects used in the tabernacle or temple, such as the ark of the covenant.
In Old Testament times, gold was used as a means of exchange in buying and selling. It was weighed on a scale to determine its value.
Later on, gold and other metals such as silver were used to make coins to use in buying and selling
When referring to something that is not solid gold, but only has a thin covering of gold, the term "golden" or "gold-covered" or "gold-overlaid" could also be used.
Sometimes an object is described as "gold-colored" which means it has the yellow color of gold, but may not actually be made of gold.
