Characteristics and Properties of Aurora Opal

Aurora Opal is a type of opal with a unique play of colors caused by light diffraction. It is characterized by a background color of blue, green, or black, and flashes of red, orange, yellow, green, and blue. The opal is composed of silica spheres and has a hardness ranging from 5.5 to 6 on the Mohs scale of mineral hardness.

  1. AURORA OPAL CHARACTERISTICS AND PROPERTIES

  2. 1. Play-of-Color: One of the most distinctive features of opals is their play- of-color, which refers to the iridescent flashes of color that appear to move and change when the stone is viewed from different angles. This phenomenon is caused by the diffraction of light by the regular arrangement of silica spheres within the opal. 2. Color Variety: Opals come in a wide range of colors, including white, black, gray, blue, green, orange, yellow, and red. The intensity and distribution of color play a significant role in determining the value and beauty of an opal. 3. Transparency: Opals can range from transparent to opaque, with many opals exhibiting varying degrees of translucency. Transparent opals are often referred to as crystal opals, while opaque opals are known as common opals. 4. Hardness: Opal has a relatively low hardness compared to other gemstones, with a rating of 5.5 to 6.5 on the Mohs scale. This means that opals are susceptible to scratching and abrasion and require gentle handling and care.

  3. 1. Body Tone: The body tone of an opal refers to the underlying color of the stone, which can range from colorless to black. Light opals have a white or light body tone, while black opals have a dark body tone. The body tone can affect the appearance and intensity of the play-of-color. 2. Formation: Opals are formed through the deposition of silica gel in cavities and fissures within the earth's crust. Over time, the silica gel hardens and forms opal. Opals can also contain water, which contributes to their internal structure and can affect their stability. 3. Metaphysical Properties: In metaphysical and spiritual beliefs, opals are associated with various properties, including creativity, inspiration, emotional healing, and enhancing intuition and psychic abilities.
