Peridot, Spinel, and Sardonyx Origin
The August birthstone, peridot, has a fascinating history. Most peridot used in jewelry today is sourced from countries such as China, Myanmar, Pakistan, Tanzania, Vietnam, and the United States. However, some peridot arrived on Earth via shooting stars, while others are found in unique locations like Peridot Beach in Hawaii, where the sand sparkles with a brilliant green hue. The ancient Egyptian island of Zabargad is the earliest recorded source of this birthstone for August. Despite its harsh conditions earning it unfavorable names like “Island of Death” and “Ophiodes” (snake island), Zabargad produced exquisite peridot that has been highly valued for centuries and remains in demand today.
Spinel is found in several places, including Tajikistan, Myanmar, Sri Lanka, Vietnam, Tanzania, and Pakistan. Some sources are known for producing spinel of vivid colors, such as hot pink and red spinel from Myanmar, representing different tones and countries. Sri Lanka is a historical Treasure Island for various gem species and varieties, such as sapphire, ruby, and garnet. Spinel is extracted in the southern part of the country, where blue, pink, and purple colors can be found. The lush rolling hills of the Central Highlands and river gravel in the Ratnapura District have been abundant sources for centuries.
Sardonyx can be sourced from various places, with India being notable for its sardonyx that contrasts its different colored layers. Other regions where sardonyx can be found include Brazil, Germany, Czechoslovakia, Madagascar, Uruguay, and the United States. In the past, distinguishing between spinels and rubies was challenging, particularly since they were often found in the same mines. The British State Crown’s large red center has recently been identified as a spinel rather than a ruby. Additionally, some of the finest “rubies” in Indian collections may actually be spinels.
