In addition to its own color and luster, gems also have more flexible displays, such as cat-eye effect, moonlight effect, 등., which give gems a more charming coat, and at the same time, greatly increase the value of gems.
1. The cat’s eye effect
Under the irradiation of light, the surface of some gemstones cut and polished in a curved shape shows a bright light band, which moves with the rotation of the gem or light, which is called the cat’s eye effect. The cat’s eye effect of gemstones is mostly caused by the parallel arrangement of needle-like, tubular or sheet-like inclusions, also due to structural characteristics or solid solution dissolution, and due to the parallel arrangement of fibrous crystals. The cat’s eye effect must meet the following three conditions:
1. The gem contains a group of acicular, fibrous, tubular, sheet-like inclusions or similar structures arranged in a dense parallel arrangement.
2. The bottom surface of the cut gemstone is parallel to the plane where the inclusions are located.
3. The gemstone needs to be polished into a curved surface. In order to achieve the best effect, the long axis direction of the gemstone should be perpendicular to the extension direction of the inclusion or parallel structure.
2. Starlight effect
Under the irradiation of parallel light, some gemstones that are cut in arcuate shapes show more than two intersecting bright lines on their surface, which are starlight effects, often four or six star lines. It is mostly caused by two or three sets of needle-like inclusions inside. The gemstone that produces the starlight effect must contain two or more groups of oriented inclusions or oriented structures inside. The formation mechanism of the star effect is the same as the formation mechanism of the cat’s eye effect. They are both caused by the refraction and reflection of the oriented inclusions or structures within the gemstone. 그러므로, when cutting the gemstone, the bottom surface of the cambered gemstone must be parallel to each group. The plane of the inclusion can produce the starlight effect. 일반적으로 말하면, gemstones of equiaxed crystal system, tetragonal crystal system and orthorhombic crystal system can appear four-pointed starlight, while gemstones of trigonal crystal system and hexagonal crystal system can appear six-pointed starlight or twelve-pointed starlight.
