Thank you for viewing. This is a natural indigo tourmaline (blue tourmaline) that I purchased at Stone Market for tens of thousands of yen, captivated by its serene indigo color. Please take a look at the fourth image, where the light of an iPhone is shone through the stone. The resolution of a Galaxy S25 Ultra captures a deep blue reminiscent of the abyss of space, and delicate inclusions unique to natural stones. This is proof of the "indigo born of the Earth," which artificial glass beads can never replicate. Size: Approximately 8mm Condition: Has a hole for stringing, as it was taken from a bracelet. Color: Deep indigo blue (changes appearance depending on the angle of light) "But," there are also fine surface scratches due to it being a natural stone. Even those are proof of the history of this stone, which has endured for tens of thousands of years. This is a gem that I want those who want to turn their lives around with quiet passion, like this deep blue, to hold in their hands.
