History and Lore
Peridot: The Green Fire
Peridot has a rich history that spans centuries and cultures. Known for its vibrant green color, peridot was believed in ancient times to possess magical properties. It was thought to bring good fortune and ward off nightmares. The gemstone was also associated with the sun and was believed to contain the fire of the sun within its green body.
In ancient Egypt, peridot was mined on the island of Zabargad, which was known as "Topazios" and was the only source of peridot for centuries. The gemstone was highly valued and often used in jewelry and amulets. In medieval Europe, peridot was considered a protective stone, and it was often worn to prevent illness and to promote vitality.
Peridot's journey from an ancient gemstone to a modern birthstone is a testament to its enduring appeal. Today, peridot is celebrated for its natural beauty and its symbolic meaning of renewal and positivity.
Spinel: The Forgotten Gem
Spinel, often mistaken for ruby or sapphire, has a long and intriguing history. Despite its similarity to these more famous gemstones, spinel has its own unique properties and charm. Historically, spinel was used in royal jewelry, and some of the world's most famous "rubies" were later identified as spinel.
One of the most notable examples of spinel's historical significance is the Black Prince's Ruby, a gemstone that adorns the British Imperial State Crown. This gem was believed to be a ruby for centuries until it was correctly identified as a red spinel. Spinel was also used in ancient Persian and Indian jewelry, where it was valued for its brilliance and durability.
Spinel's role as an August birthstone has brought renewed attention to this gemstone. It is celebrated for its versatility in color and its ability to mimic other gemstones while maintaining its own unique identity.
