According to Biblical Lore the deep violet-hued Amethyst has symbolized protection, peace and tranquility. Aquamarines were believed to have originated from the jewel caskets of sirens, washed ashore from the depths of the sea. They were considered sacred to Neptune, god of the sea. This association with the sea made it the sailors' gem, promising prosperous and safe voyages as well as protection against perils and monsters of the sea. They wore aquamarine amulets engraved with the god Poseidon on a chariot.
Diamonds are a wonder of nature.
Their cold sparkling fire has held us spell-bound for centuries, inspiring rich passionate myths of romance, intrigue, power, greed, and magic. Ancient Hindus, finding diamonds washed out of the ground after thunderstorms, believed they were created by bolts of lightning. In our place and time, the diamond is a symbol of enduring love, and often grace engagement rings. Venus, known as the Goddess of Love is perhaps another reason the Diamond became the symbol of love. Several famous historical artifacts were made of emeralds.
