The inner diameter of the ring is approximately 1 centimeter 6 millimeters, and the weight is 3 grams. Thank you for viewing. I purchased this ring as a self-motivating item, but I am selling it now that it has served its purpose. The ring itself currently sells for around 160,000 yen. The engraving reads "L’indole plasma il destino," which is Italian for "Character, thought, action, and emotion shape the future." I ordered this item while consulting with the staff about the translation, during a time when I strongly felt that I wouldn't move forward unless I took action, even on things that made me hesitate. I hope it will empower its next owner.
