Huge Natural Red Star Ruby - 6 Rays - 136.8 ct – Rough- 27.36 g

The natural red star ruby is a rare and fascinating variety of corundum prized for its asterism, a star-shaped light effect that typically exhibits six rays but can occasionally display more. This optical phenomenon occurs when needle-like inclusions of rutile align within the gemstone, scattering light in a star pattern that moves as the stone is rotated. A huge natural rough star ruby weighing over 130 carats offers a dramatic display of this effect combined with the intense red color that signifies high value. Rough specimens allow gemologists and collectors to study the mineral's natural form before cutting and polishing. Such star rubies are not only valued for their beauty but also for their unique optical properties and rarity within the gem world.
