Product｜Star Sapphire. Star Corundum｜<<Traditional Heating>> Produced in Sri Lanka - the most famous source of starlight. The texture of the gemstone is milky and translucent, and there is a very obvious crystal growth pattern on the surface that looks like a circuit board. Star sapphire is an evolution of sapphire. This is because if the needle-shaped crystals that are common in sapphire grow a lot and grow in the same direction, the whole row of needle-shaped inclusions will reflect the light when facing the light, and radiate towards the six angles of the "hexagonal crystal system". From a distance, it looks like starlight, hence the name. Star sapphire is formed when the inclusions in the sapphire grow in the same direction, so it is very rare. Star sapphire is one of the gemstones with seriously underestimated prices. In this era of extreme scarcity of sapphires, the value-added potential of star sapphires is extremely great. This very good 6-beam star sapphire is a beauty that gem collectors cannot miss. Star sapphire belongs to corundum, and its hardness is 9, second only to diamond.
