The City Guard signet ring, besides being a lovely gold ring given to Geralt by Vincent Meis in Chapter II only after the witcher finds irrefutable proof that the captain is not involved with Salamandra. It allows entry into one of two semi-restricted areas within the Temple Quarter: the dike and St. Lebioda's Hospital. Although this ring can not be bought initially, once acquired, it can be sold and then repurchased, hence the prices below.
