Kostner, one of Italy's most popular athletes, has finally tasted Olympic success after five European titles and several world medals.
She flopped at Turin in 2006, where she finished ninth after going in as favourite, and placed 16th at Vancouver in 2010.
Italy won the bronze medal in the biathlon mixed relay on Wednesday.
The Italian team of Dorothea Wierer, Karin Oberhofer, Dominik Windish and Lukas Hofer came behind gold medallists Norway and the Czech Republic.
Earlier in the Games, short-track skater Arianna Fontana won two individual medals, bronze in the 1,500-metres and silver in the 500m, and helped Italy come third in the 3,000m relay event.
Italian skier Christof Innerhofer won two more medals: silver in the men's downhill and bronze in the super combined.
Armin Zoeggeler's bronze in the luge is the other medal Italy has won in Sochi so far.
