"Kristallen den Fina" ("The Fine Crystal") is a traditional Swedish folk song considered to be from the village of Skattungbyn in the province of Dalarna. Its author is not known. Many arrangements of the song have been written for various choral groups. One early arrangement of the piece for men's voices was by Otto Frederik Tullberg in 1840. The language used in Kristallen den Fina relies on a poetic structure and uses older, folk language, rather than conversational Swedish. Thematically, the song reflects a sense of longing and romance between a couple.
