Color and Appearance of Almandine Spinel
Almandine spinel exhibits a striking deep red to purplish-red hue, often described as reminiscent of a fine red wine or pomegranate seeds. This rich coloration is one of its most distinguishing features, setting it apart from other gemstones. The intensity of its color can vary, ranging from lighter pink-red shades to deep, saturated reds with a slight purple undertone.
Crystal Structure
Almandine spinel belongs to the cubic crystal system, forming octahedral crystals. This structure gives the gemstone excellent optical properties, including a high refractive index that contributes to its brilliant luster. The crystal faces are typically smooth and well-formed, making it a popular choice for faceted gemstones.
Physical Characteristics
With a hardness of 8 on the Mohs scale, almandine spinel is quite durable, making it suitable for everyday wear in jewelry. It has no cleavage, which further enhances its toughness. The gemstone also exhibits a vitreous to sub-adamantine luster, giving it a glass-like shine that catches the eye.
Unique Features
One of the most notable characteristics of almandine spinel is its high dispersion, which creates a captivating fire effect as light passes through the stone. This property, combined with its excellent clarity and lack of inclusions, results in a gemstone with exceptional brilliance and sparkle. Additionally, almandine spinel is known for its ability to display asterism, a rare optical phenomenon that creates a star-like effect on the surface of some specimens when cut as cabochons.
