Yellow sapphire(Pukhraj)

Yellow sapphire is one of the fancy sapphires of the corundum group. It refers to the yellow color of the corundum. It is a part of the 9 Navratan gemstones. Its finest color is yellow to orange-yellow with medium tone and vivid saturation. Their demand varies depending on the fashions in the market.

Their main sources are Sri Lanka and East Africa. They are generally heat treated. Thailand is the largest center for its treatment. Its treatments include lattice diffusion and heat treatments. It can be radiated to improve its color but the stone loses its new color when it's exposed to the sun.

These can also be made in labs using various methods. Only a trained gemologist can tell the difference between a synthetic and a natural yellow sapphire. Its various imitations include glass, doublets, topaz, citrine, Cz, and so on.

Astrologists say that Pukhraj holds the power of the planet of Jupiter. The stone is believed to embark wisdom, power, and cleverness in the mind of the owner. It is generally worn by people of Pisces (Meen Rashi) and Sagittarius (Dhanu Rashi). People prefer to wear Pukhraj with good clarity and brilliant yellow color.
