Facts about Untreated Sapphires
Let’s explore key facts about abou untreated sapphire gemstones:
  • Untreated sapphires are exceptionally rare. Only about 0.5-1% of sapphires discovered are of gem quality without any treatment. This rarity makes natural, untreated sapphires far more valuable than treated ones.
  • Untreated sapphires come in a rainbow of colors beyond just blue. They can be found in pink, peach, purple, yellow, orange, green, teal, and even colorless varieties. The different colors are caused by trace elements within the mineral corundum.
  • On the Mohs scale of hardness, sapphires score a 9 out of 10, making them the third hardest natural mineral after diamonds and moissanite. This exceptional hardness makes untreated sapphires very durable for use in jewelry.
  • Star sapphires are a unique variety of untreated sapphires that display a star-like pattern when cut into a cabochon shape. This effect is caused by the presence of tiny needle-like inclusions of rutile within the stone.
  • Untreated sapphires over 5 carats are considered exceptionally rare and valuable, especially if they have good clarity and color distribution.
  • The most prized blue shades in untreated sapphires are known as 'Kashmir' (a velvety saturated blue) and 'Ceylon' (a smooth royal blue), named after the regions where they are traditionally mined.
  • Some of the countries where untreated sapphires are mined include Sri Lanka, Myanmar, Madagascar, Australia, and the United States.
  • Experts generally recommend purchasing untreated sapphires for their rarity, value, and natural beauty, especially for colors like yellow and orange where the untreated versions are considered superior to treated ones.
