Jacinth & Amethyst

Jacinth

Jacinth, from the Greek word hyacinth, is a red transparent variety of zircon.

Jacinth, like a lot of other zircon, has been used since biblical times. It has also shown up as an ornamental stone in the weaponry and armor of other cultures.

Jacinth is better suited to items like pendants, necklaces, brooches, and earrings than it is to bracelets.

Many ancient cultures believed jacinth would protect them from personal danger. It was also believed to protect property from theft. Some thought that is could ward off the evil of witchcraft. Many believed that it would dull in color if the wearer was sick. 

Amethyst

Amethyst is a violet variety of quartz often used in jewelry. The name comes from the Greek meaning not intoxicated. The ancient Greeks and Romans wore amethyst and made drinking vessels of it in the belief that it would prevent drunkenness.
Amethyst was used as a gemstone by the ancient Egyptians and was largely employed in antiquity as engraved gems.
Up to the 18th century, amethyst was included in the most valuable gemstones along with diamond, sapphire, ruby, and emerald. However since the discovery of extensive deposits in locations such as Brazil, it has lost most of its value.
