Orange andesine is a variety of the plagioclase feldspar mineral, specifically a type of labradorite, which falls within the andesine range of the solid solution series. It is known for its vibrant orange to red-orange color, which can resemble that of other gemstones like sunstone and is often used in jewelry.
Characteristics and Properties
Color: Orange andesine ranges in color from a pale orange to a rich red-orange. The color is often caused by the presence of copper inclusions, similar to what is found in sunstone.
Composition: Andesine is part of the plagioclase feldspar series and is composed primarily of sodium and calcium aluminum silicates. Its formula is typically represented as (Na,Ca)(Si,Al)4O8.
Hardness: It has a Mohs hardness of around 6 to 6.5, making it relatively durable for use in jewelry, though it should still be treated with care to avoid scratches.
Luster and Transparency: Orange andesine exhibits a vitreous (glassy) luster and can range from transparent to translucent.
Crystal System: It crystallizes in the triclinic system, typically forming in tabular or blocky crystal habits.
Sources and Treatments
Natural Sources: Natural deposits of andesine can be found in locations such as Mongolia, Oregon (USA), and South Africa. However, the most noted sources for gem-quality orange andesine have been Mongolia and the Democratic Republic of Congo.
Treatments: Some orange andesine on the market has been subject to treatments to enhance its color. Diffusion treatment with copper has been a known method to enhance the red and orange colors of this gemstone. It is essential for buyers to inquire about the origin and treatment status of andesine when purchasing.
Identification and Differentiation
Orange andesine can sometimes be confused with other feldspars, such as sunstone or even certain types of labradorite. Its identification involves examining its optical properties and using tools like a refractometer to measure its refractive index, which typically falls between 1.543 to 1.560. Pleochroism (different colors seen from different angles) is another feature that can help in its identification.
Market and Uses
Jewelry: Orange andesine is primarily used in jewelry, including rings, earrings, necklaces, and pendants. Its vibrant color makes it a popular choice for unique and eye-catching pieces.
Value: The value of orange andesine varies based on factors like color, clarity, cut, and whether it is treated or natural. Untreated stones with a deep, uniform color and good clarity are generally more valuable.
