Before you buy a Yellow Sapphire (Pukhraj), it helps to understand what you are actually looking at. Known in Sanskrit as Pukhraaj and worn as one of the nine sacred Navratna gems, Yellow Sapphire is also a fascinating gemstone in its own right — one of the hardest and most durable stones on earth. This information guide covers its gemological facts, colour range, common treatments, price and the smart advantages of buying a loose Yellow Sapphire.
What is Yellow Sapphire?
Yellow Sapphire is the yellow variety of the mineral corundum (the same family as ruby and blue sapphire). It is prized both as fine jewellery and as the astrological gemstone of Jupiter (Guru). Sapphire as a mineral occurs in many colours — pink, yellow, green, purple, orange, blue-green and even black — but the pure yellow variety is what is worn as Pukhraj.
Yellow Sapphire – Key Gemological Facts
| Property | Detail |
|---|---|
| Mineral | Corundum |
| Colour range | Light lemon-yellow → vivid saturated yellow → deep orange-yellow |
| Hardness | 9 on the Mohs scale (extremely durable) |
| Astrological name | Pukhraj / Pukhraaj |
| Ruling planet | Jupiter (Guru) |
With a hardness of 9 on the Mohs scale, Yellow Sapphire is second only to diamond — making it ideal for everyday wear in rings and pendants without scratching or damage.
Treatment: Heated vs Unheated Yellow Sapphire
This is one of the most important things to know: most yellow sapphires are heat-treated to improve their colour, and many are also treated with beryllium through a lattice-diffusion process. These treatments are common in the jewellery market. However, for astrology, a natural, unheated Yellow Sapphire is considered far superior — unheated stones with good saturation are rare and much more valuable, and carry the purest planetary energy. Always ask whether a stone is heated or unheated, and insist on a lab certificate that states it.
Yellow Sapphire Price
The price of good-quality Yellow Sapphire generally ranges from around ₹5,000 to ₹10,000 per carat, and can go significantly higher for rare unheated stones with strong colour and clarity. Price depends on colour, clarity, carat weight, origin and treatment. Buy Certified Yellow Sapphire Online
