Ct. 1.15 Star Sapphire Pair Cabochons - Height: 7 mm - Width: 5 mm- 0.23 g

DESCRIPTION OF FEATURES Family: Corundum; Variety: Sapphire; Geographic origin: Thailand; Shape: oval; Cut: cabochon; Optical effect: asterism with a star visible under direct light, natural or artificial; Treatment: heated; Mohs hardness: 9.00; Transparency-Clarity: translucent with natural inclusions. The star sapphire differs from ordinary sapphire by the phenomenon known as ASTERISM, which superficially appears on the stone when it is illuminated with direct light. To obtain this optical effect, the stone must be cut cabochon, so as to collect light and then reflect it outward. Contrary to common belief, star sapphire forms naturally, and is a variety of corundum with needle-like inclusions that cause, indeed, the formation of a star on the surface. Photographic Settings All items are photographed individually with a high-resolution macro lens in an indoor setting using LED lighting at 5000 Kelvin, the color temperature closest to sunlight. Photos are not altered, except for cropping.
