Tiffany Atlas Ring Size 11.5, width approximately 6.12mm, 5.45g Authentic. Newly polished. Almost flawless, like new. Polishing (removal of scratches, dirt, etc.) Removal with high-frequency ultrasonic cleaning solution. Cleaning with an ultrasonic cleaner and precious metal cleaning solution. The actual item is much cleaner than the photos. When measuring the size: If you measured 11.5 using a 3mm wide band, a 6mm wide band might feel a bit tight, so a size 0.5 to 1 size larger, around 12 to 12.5, is often a better fit. Please use this as a reference. - Brand: Tiffany & Co. - Year of Manufacture: 1995 - Material: Silver 925 Thank you for viewing. Size...11.5 Accessories...None
