Ring of Acorns

The Ring of Acorns is a magical artifact and an heirloom of the House of Acorn. It possesses healing properties and can also grant wishes. Amy Rose used the Ring to wish herself older. However, the price of her aging was all the energy contained within it. Thus, the Ring of Acorns has become useless, valuable only as an heirloom of the house.

While not named as the Ring of Acorns, a ring was seen briefly in the SatAM cartoon during the two-part "Blast to the Past" episode. In this episode, Princess Sally was wearing the ring when she met her father in the past, the ring serving to verify that she was indeed who she claimed to be. The ring was however referred to as the 'Royal Signet', and not as the Ring of Acorns, and appeared to have no mystical properties.
