London (CNN) - History was made in the boxing ring Thursday, as Great Britain's Nicola Adams became the first woman ever to win a full Olympic gold and Team USA's Claressa Shields followed with the middleweight title.
"I think I will wear (the gold medal) every day for the first year," Shields said.
Adams' triumph in the flyweight final over China's Ren Cancan was greeted by ear-splitting screams of delight by the home crowd.
"It sounds really good, it's like a dream come true," Adams said. "I've wanted this all my life and it's finally come true. I'd really like to thank all the supporters here and elsewhere. I'm so happy and overwhelmed with joy right now."
Shortly after, Ireland's Katie Taylor came out on top in the first Olympic women's lightweight final, making a spirited comeback in the last round to beat Russia's Sofya Ochigava by 10 points to 8.
Taylor fell to her knees in joy and relief as the victory was announced, giving her country its first gold medal of the Games, before doing a lap of honor around the ring draped in the Irish flag.
Shields' 19-12 victory against Russia's Nadezda Torlopova is a remarkable achievement for the 17-year-old from Flint, Michigan - and makes her the first American woman to take an Olympic boxing gold.
Flyweight Marlen Esparza, from Texas, took a bronze.
