I am selling this item to organize my collection. I only displayed and admired it; I never wore it. Natural Stone: Red Phantom 3-4 mm, Inner circumference: 13.5 cm I bought this intending to make a design bracelet, but I ended up making something different, so I didn't use this. The transparency of the crystal is very high. The shape of the phantom is also clearly visible, so I will sell it to someone who needs it(^^) * Please note that this is a natural stone. Please understand that it may have natural cracks, dents, chips, and inclusions. Thank you for looking.
