Geological Formation and Sources
Each of the August birthstones is formed through unique geological processes and is found in specific locations around the world. Understanding these processes and sources helps to appreciate the rarity and beauty of these gemstones.
Peridot
Peridot is a magnesium-rich silicate mineral that is formed in the Earth's mantle and brought to the surface through volcanic activity. It is most commonly found in igneous rocks, particularly in basalt and peridotite. Peridot is known for its bright green color, which is caused by the presence of iron. The most significant sources of peridot include countries like the United States (particularly in Arizona), Egypt, and Myanmar.
Sardonyx
Sardonyx is a type of chalcedony, which is a form of quartz. It is formed when silica-rich water seeps into cavities in rocks and cools over time, depositing layers of different colors. The red-brown and white stripes characteristic of sardonyx are the result of impurities and different mineral content in the layers. Sardonyx is primarily found in regions like India, Brazil, and the United States. These areas are known for their rich deposits of chalcedony and have been important sources of sardonyx for centuries.
Spinel
Spinel is a mineral that forms in a variety of geological settings, including metamorphic and igneous rocks. It is most commonly found in areas where there has been significant tectonic activity, as this helps to bring the mineral to the surface. The most famous sources of spinel include Sri Lanka, Myanmar, and Vietnam. These countries have a long history of spinel mining and are known for producing high-quality stones in a range of colors.
Gemological Properties
Understanding the gemological properties of the August birthstones is essential for both collectors and jewelry buyers. These properties determine the stone's durability, appearance, and suitability for different types of jewelry.
Peridot
Peridot is a relatively soft gemstone, with a hardness of 6.5 to 7 on the Mohs scale. This makes it suitable for jewelry but requires careful handling to avoid damage. Peridot is known for its vibrant green color, which can range from yellow-green to deep olive-green. It has a refractive index of 1.65 to 1.69 and is typically transparent to translucent. Peridot is also known for its pleochroism, which means that it can display different colors when viewed from different angles.
Sardonyx
Sardonyx has a hardness of 6.5 to 7 on the Mohs scale, making it durable enough for everyday wear. It is a banded chalcedony, with the red-brown and white stripes being a defining characteristic. Sardonyx has a refractive index of 1.48 to 1.53 and is typically translucent to opaque. It is often used in cabochon form, which means that it is not faceted but instead polished to a smooth, curved surface.
Spinel
Spinel is a relatively hard gemstone, with a hardness of 8 on the Mohs scale. This makes it more durable than peridot and sardonyx and suitable for a wide range of jewelry designs. Spinel is known for its brilliance and fire, which are similar to those of diamond and other precious gemstones. It has a refractive index of 1.718 to 1.834 and is typically transparent to translucent. Spinel is available in a wide range of colors, including deep red, vivid pink, orange, blue, and black.
