What is "hnoss"

In Norse mythology, Hnoss ( Old Norse "treasure") is the daughter of Freyja and Óðr, and the almost identical sister of Gersemi. She is the goddess of desire and lust. In Gylfaginning it says, "She is so lovely that whatever is beautiful and valuable is called treasure from her name." Some have even translated her name as "jewel" or "gem".
