5.09ct Natural Grandidierite

There is no doubt that Grandidierite is a very expensive gemstone with eye-clean transparent examples easily reaching $20,000. The vast majority of Grandidierite gemstones sold are described as translucent or transparent but with many inclusions or flaws. However these gemstones are genuinely quite beautiful with the faceted cuts displaying the change of color from green to blue to clear and revealing charming clouds and swirls within.
