The square amethyst stone is a half inch across and in very nice condition. The ring is about 20 years old and appears to have been refurbished at one point. The JH signature is barely legible but please be assured that this is an authentic John Hardy piece. Please refer to the photos for the measurements and signature markings. The ring is a 4.75 and can be resized.
