Egypt is rich in gold, and silver is much rarer than gold. The ancient Egyptians mastered the superb gold processing technology very early. Gold is mined in the eastern desert and Nubia to decorate the heads, necks and arms of Pharaoh and his courtiers. The jewelers in Pharaoh's period didn't realize the value of precious stones, so they used a lot of secondary precious stones, such as feldspar, jade, turquoise, purple and chalcedony, to process exquisite ornaments. On the shores of the Red Sea, people also collect mother-of-pearl and shells as decorations.
