Bicolor sapphire is a rare and unique gemstone that has gained popularity among jewelry enthusiasts in recent years. This gemstone is known for its stunning color variations, which create a stunning display of hues on any piece of jewelry it is set on. Bicolor sapphire is a type of corundum, which is a mineral composed of aluminum and oxygen. It is a variety of sapphire, which is the second-hardest mineral on Earth after diamond. In this article, we will explore the formation, properties, and characteristics of bicolor sapphire, as well as its use in jewelry making.
Formation of Bicolor Sapphire:
Sapphire is formed under high-pressure and high-temperature conditions within the Earth's crust. The mineral is commonly found in metamorphic rocks and alluvial deposits in different parts of the world. Bicolor sapphire is formed when two different colors of sapphire are present in a single crystal.
The conditions under which bicolor sapphire is formed are not entirely understood, but it is believed that the color variations occur due to changes in the chemical composition of the mineral during its growth. This can happen when the sapphire crystal is exposed to different mineral environments as it grows.
Properties and Characteristics of Bicolor Sapphire:
Bicolor sapphire is characterized by its two distinct colors, which are often separated by a sharp boundary. The colors can be evenly distributed within the gemstone, or one color can dominate over the other. The most common color combinations are blue-green, blue-yellow, and blue-purple. The color of bicolor sapphire is determined by the amount and type of impurities present in the crystal.
These impurities can include iron, titanium, chromium, and vanadium, among others. The presence of these impurities can also affect the gemstone's transparency, with some bicolor sapphires being more opaque than others. Bicolor sapphire is a hard and durable gemstone, with a Mohs hardness rating of 9. This makes it suitable for use in all types of jewelry, including rings, earrings, necklaces, and bracelets. It is also resistant to scratches and abrasions, which helps it maintain its luster over time.
