Formation and Phenomena

Formation of Star Sapphire

star sapphires are formed when corundum crystals undergo a geological process known as asterism. During the formation process, needle-like inclusions align in a specific orientation, intersecting to form a star-like pattern on the surface of the gemstone. These inclusions, known as rutile needles, refract light and create the stunning six-rayed star phenomenon.

Asterism in Star Sapphires

Asterism is the phenomenon responsible for the star pattern visible on the surface of star sapphires. The rutile inclusions align parallel to each other within the crystal structure, reflecting light in a way that forms a six-rayed star. The star can be observed when the gemstone is viewed under a single light source, such as a spotlight or a direct beam of sunlight.

Color-Change Phenomenon

Color-change star sapphires exhibit a fascinating optical phenomenon where the gemstone’s color appears to change under different lighting conditions. These sapphires may appear blue in natural daylight and transform into shades of purple or violet under incandescent light sources. The color change is attributed to the presence of different trace elements within the crystal structure.

Parti-Color Phenomenon

Parti-color star sapphires showcase a captivating combination of colors within the same gemstone. This phenomenon occurs when sections of the crystal contain varying concentrations of different trace elements, leading to distinct color variations. The parti-color effect adds uniqueness and visual interest to these extraordinary gemstones.
