Iolite, also known as cordierite, is a captivating gemstone that has its origin from the Greek word ‘ios’ which means ‘violet’. This beautiful gemstone is a variety of orthorhombic mineral and is typically blue, grey-blue, or violet-blue in color. Iolite is a popular gemstone that is widely used in jewelry making and has been used for thousands of years for its beauty, durability, and healing properties. Iolite is primarily found in Brazil, Madagascar, India, and Sri Lanka in large quantities. In this article, we will explore the qualities and properties of iolite as well as its history and popularity in the jewelry industry.
History of Iolite:
The history of iolite dates back to ancient times, where it was used as a navigational tool by Viking sailors. It was believed that when viewed through an iolite lens, the sky would appear to be polarized, which helped sailors to determine their position at sea. This made iolite an important gemstone for sailors and explorers.
In addition to its navigational uses, iolite was also used in various cultures for its healing properties. In ancient Egypt, it was believed that wearing iolite could help to improve eyesight. In India, iolite has been used for centuries to enhance intuition, spiritual awareness, and psychic abilities.
Iolite also has a strong connection to the Greek mythological figure, Dionysus. According to legend, Dionysus became angry with humans and turned them into drunken, wild beasts. However, he spared the faithful followers and turned them into iolite, which was believed to have the power to ward off drunkenness. Today, iolite continues to be a popular gemstone in the jewelry industry, and its use in fine jewelry is on the rise, especially in engagement rings.
Iolite has a unique set of physical properties that make it desirable for jewelry making. It belongs to the orthorhombic mineral category, which makes it one of the few gemstones that can display different colors when viewed from different angles. This effect is known as pleochroism and is one of the distinct features of iolite.
Iolite typically has a hardness of 7-7.5 on the Mohs scale, which makes it a durable gemstone that can withstand daily wear and tear. It also has a refractive index of 1.522-1.578, which means that it has moderate to strong dispersion, giving it a beautiful and appealing appearance.
Iolite is formed through a metamorphic process that occurs in mineral-rich rocks such as granite, where the gemstone forms as a result of the pressure and heat that is generated during the process. It is usually found alongside other gemstones like quartz, feldspar, and garnet.
Colors and Varieties:
Iolite has unique colors that range from pale blue, grey-blue, to deep violet-blue. Iolite that has a pale blue color is referred to as water sapphire, while the darker violet-blue variety is known as the Viking stone. The most common variety of iolite is blue, which makes it popular as an engagement ring stone.
The intensity and hue of the color of iolite can vary depending on the light source, the angle of observation and the cut of the stone. When viewed from different angles, iolite can display different colors, making it a popular choice for jewelry designers.
Like other gemstones, iolite can have inclusions, or internal flaws, which can affect its appearance and value. Some of the common inclusions that can be found in iolite include mineral deposits, fractures, and other impurities. The presence of inclusions may affect the clarity and transparency of the stone, which can, in turn, affect its value. Inclusions can also provide a unique and interesting character to the gemstone. Some inclusions can provide a cat's eye or asterism effect on the stone, which makes it very appealing to collectors.
Iolite is a highly prized gemstone that is used in the jewelry industry to make various pieces of jewelry. Its unique colors, durability, and affordability make it a popular choice for designers looking to create gorgeous pieces of jewelry. Iolite is often used as a center stone for engagement rings, and also as accent stones alongside diamonds or other colored gemstones.
It is also used to create pendants, earrings, and bracelets, and it can be cut in various shapes and sizes to suit different designs. When designing jewelry, iolite is often paired with gold, silver or platinum to create elegant and timeless pieces. The stone can be set in various settings, including prong, bezel, or cluster settings, depending on the design and desired effect.
Iolite’s affordability makes it a popular choice for mass-produced jewelry, as it is easier to source than other gemstones like diamonds or sapphires. It is also a practical choice for consumers looking for beautiful and affordable gemstones.
