Iolite Quality & Price

The quality and value of any stone is evaluated on certain parameters.

  • Origin-

    Iolite gemstone is mined in Myanmar, India, Brazil, Madagascar, Norway and Sri Lanka. Amongst all these origin varieties, stones from India and Madagascar are highly sought-after for their superior quality.
  • Color-

    Iolite crystals are trichroic, which means that three different colors are seen in the same gem, depending on the angle you view it from. Most stones appear blue to violet in color but can appear to be clear, gray, or yellow when viewed from other directions. The color on the top is given the most importance. Gemstones with consistent blue-violet color on top are preferred to those with yellow or grey tints. The blue-violet color of the stones ranges from very light blue to deeper blue, usually with a beautiful purplish tinge. A valuable piece of Iolite will have a soft saturated violet-blue color whereas less valuable gems have a faded purple color.
  • Clarity-

    Iolite crystals are usually transparent to translucent. Iolite can have visible inclusions like fingerprints, minerals, metallic platelets etc. Stones with no or lesser visible inclusions are preferred to highly included stones.
  • Cut-

    Iolite displays pleochroism, meaning that it shows three distinct colors when seen from different angles, so cutting an Iolite stone becomes tricky. Ideally, Iolite is cut in a manner that the gemstone looks consistently blue-violet and without any yellow tints when viewed from the top.
