Description
This lot consists of thirteen (13) natural yellow sapphire gemstones, collectively weighing 41.35 carats, sourced from Balkacha, Thailand — a region known for producing vibrant yellow sapphires similar to other Southeast Asian sapphire deposits. Yellow sapphire (commonly called “Pukhraj” in the gem and astrological trade) belongs to the corundum mineral family, the same species as ruby and blue sapphire, and ranks 9/10 on the Mohs hardness scale, making it ideal for rings, pendants, bracelets, and custom jewelry settings.
The color of yellow sapphire ranges from soft pastel yellow to intense golden hues, often influenced by trace amounts of iron in the crystal structure. Thai-origin yellow sapphires typically show rich golden colors prized by gem collectors and jewelry designers alike.
