Size: Approximately 13mm Inner diameter: Approximately 16.5cm This is an Iolite Sunstone with many inclusions. It's a large 13mm bead for this stone. Iolite is a captivating stone that makes you want to collect many due to the inclusions... it's a rabbit hole... There are still some imperfections, and the original price was around 68,000 yen, so I'm not considering a price lower than this. The lepidocrocite, which looks like a rainbow shining from the inside, is prominent, and I think it's a refined beauty. The color may appear different depending on the display and environment. Please understand. The photos were taken in natural sunlight on a clear day. This is a natural stone. There may be cracks, inclusions, and small chips or scratches. I try to describe them as much as possible, but please refrain from purchasing if you are sensitive or seek perfection. Safe! Shipped via Mercari with tracking. Due to the high price, it will be shipped via Takkyubin Compact. Depending on the packaging size, the shipping method will be changed between "Yu-Yu" and "Raku-Raku" without notice. *Recycled packaging materials will also be used.
