While there is some discoloration, there is No pitting, it always looks worse with a close up digital image. No one but the wearer will know. Very sound pin stem. 3 1/8" X 2 1/8".
UPDATE: one day after listing this fab brooch for $126, it was found to have a small split at upper right applied scroll. It is now a low, low price of $59! Still very wearable and sound.
