The Silk Road
This is a much bigger work but of the same subject work.
The Arabian Gulf (Persian Gulf) has a long history of "Pearling".These gems of great beauty were worn by both men and woman. In the Muslim world the Pearl is the symbol of perfestion. In the Hindu world the Pearl is a symbol of the Moon. Red Coral is found in the Mediterranean Sea and was put around the necks of babies to ward-off evil spirits. Sadly it is now endangered by the evils of the modern world.
