What is the name of Freyja's necklace forged by dwarves?

What is the name of Freyja’s necklace forged by dwarves? It is Brísingamen.

Brísingamen is the famous necklace, or torc, belonging to Freyja, the Norse goddess associated with love, beauty, fertility, magic and war. Its name is Old Norse, and the second element, men, means an ornamental neck-ring or torc made from precious metal.

The necklace appears in several mythological traditions. In Þrymskviða, Freyja’s fury shakes the halls of the gods when the giant Þrymr demands to marry her in exchange for returning Thor’s stolen hammer. Thor later borrows Brísingamen while disguising himself as Freyja to attend the wedding.

Another story, preserved through material connected with the Prose Edda, tells how Loki steals the necklace. Freyja enlists Heimdallr to recover it, and the two adversaries fight in seal form at Singasteinn. Heimdallr wins and returns the treasure.

A later tale, Sörla þáttr, explicitly says four dwarves forged the necklace, but details differ across sources. Mjölnir, Gungnir and Draupnir are also famous treasures, yet they belong to Thor, Odin and the gods’ treasure tradition rather than identifying Freyja’s necklace.
