History and Lore
August Birthstones
August is one of the months with the most diverse array of birthstones, including peridot, sardonyx, and spinel. This variety reflects the rich historical and cultural background of these gems.
Peridot
Peridot has a long and storied history. It is one of the few gemstones that can be found in both Earth and space. Peridot is formed from olivine, a mineral that is carried to the surface through volcanic activity. Historically, peridot was known as the "evening emerald" due to its bright green color. Ancient civilizations, including the Egyptians and Romans, prized peridot for its beauty and believed it to have protective powers.
Peridot was also believed to be a stone of good luck and was often worn as a protective charm. In medieval times, it was thought that peridot could ward off nightmares and negative energies. Some sources even suggest that Cleopatra’s famous emerald collection may have actually been peridot, given the similarities in color and appearance.
Sardonyx
Sardonyx, a type of onyx, has a red-brown base with white banding. It is one of the oldest known gemstones, with a history dating back over 4,000 years. The name "sardonyx" is derived from "sard" (a type of quartz) and "onyx," referring to its banded appearance.
Sardonyx was highly valued in ancient Egypt and Rome. It was often used in signet rings and amulets, and it was believed to bring strength and courage to the wearer. The stone was also associated with the sun and was used in religious and ceremonial contexts.
Spinel
Spinel is a relatively recent addition to the August birthstone list, having been officially recognized in 2016. For centuries, spinel was mistaken for ruby and other red gems. However, once its unique properties were understood, spinel gained appreciation for its brilliance and color range.
Spinel is found in a wide array of colors, including red, pink, blue, and black. It has a high refractive index and excellent luster, making it a desirable gemstone for jewelry. The stone was historically used in royal jewelry and was particularly popular in Europe during the 18th and 19th centuries.
The addition of spinel to the August birthstone list was a response to the growing demand for more diverse and affordable gemstone options. It allows for greater flexibility in jewelry design and provides August-born individuals with a wider range of colors and styles to choose from.
November Birthstones
November has two official birthstones: topaz and citrine. Both are known for their warm, inviting colors and their positive energies.
Topaz
Topaz has been revered for centuries for its clarity and brilliance. It is found in a wide range of colors, including colorless, yellow, orange, pink, and blue. The most common and well-known variety is golden topaz, which has a warm, sunny hue.
Historically, topaz was believed to have magical properties. The ancient Greeks thought it could increase strength and invigorate the body. In medieval Europe, topaz was used to ward off spells and dispel anger. In India, it was believed that wearing topaz above the heart could bring long life, beauty, and intelligence.
One of the most interesting aspects of topaz is that many of the blue topaz stones seen in jewelry today are not naturally blue. Instead, they are colorless topaz that has been treated with irradiation and heat to produce a lasting blue color. This treatment enhances the gem’s natural beauty and makes it more accessible to a wider audience.
Citrine
Citrine is a variety of quartz known for its golden yellow to orange color. It is a relatively abundant gemstone, which makes it more affordable than many other birthstones. Citrine has been used for centuries in jewelry and decorative objects.
Like topaz, citrine is associated with positive energy and warmth. It is believed to promote joy, confidence, and creativity. In some cultures, it was also thought to have protective properties, warding off negative influences and bringing good fortune.
Citrine is often found in Brazil, where it is mined in large quantities. The stone is also popular in fashion jewelry due to its durability and affordability.
