Human history includes a history of gemstones believed to provide protection, healing and metaphysical attributes. The ancient Romans used amber for protection. Amethyst is mentioned in the Old Testament as aiding in divination. Rubies were used by kings and leaders for protection and to aid in their decisions. The Greeks believed that diamonds came from stars.
In the European and Mediterranean areas, handmade metaphysical gemstone jewelry reflected the practice of Christianity. Some of the pagan meanings of stones transferred to Christian interpretations. Since garnets were supposed to stop bleeding, soldiers and Crusaders wore garnets for protection during their travels and into battles. Soldiers also wore amethyst for its stated quality of protecting against evil and providing clear thinking.
Handmade metaphysical gemstone jewelry makes its place in the business world. Some believe they will be afforded protection during air travel with malachite or garnets. For dealing with stress in the business world, jewelry made with mugglestone is said to provide a sense of calmness, especially in legal situations. Citrine is the stone of communication and success. Handmade jewelry with citrine is worn by people who want to make their business profitable and enjoyable. For business workers dealing with eye fatigue, emeralds in handmade jewelry carries the legend of helping eyes, even to the point of seeing into the future.
Many metaphysical gemstone legends and lore appear for everyday occasions. For physical protection, some wear jewelry made with peridot and agate. Diamonds are said to offer protection against poison (though don't test that claim literally). The ancient attributes of amethyst for divinations may appear on a bishop's ring or under someone's pillow for dreams of the future. Amethyst may surface in handmade jewelry at meetings for people with addictions to alcohol or drugs. For protection from radiation, some wear jewelry containing amber rutilated quartz. Rubies supposedly help eliminate toxins and chemicals.
