Authentic Tiffany & Co. Marked 925 for sterling silver. Hallmark on the inside of the band as well as underneath the ball. Retired design in that Tiffany & Co. only makes this ring in gold and rose gold now... they do not make this in sterling silver. Approximately a size 6. Normal scratches due to wear, but nothing major to note. Timeless and classic. Great for everyday wear. Perfect cocktail or statement-making ring.
