Asking Help with a More Accurate Rendering

Hello! In an attempt to make my writing more lore-authentic, I am struggling with a Sindarin female name.

I am attempting to render the name, "Heart's Desire". Several translations are conflicting in their results, and I am striving to be as accurate as possible.

Any suggestions would be greatly appreciated!

I would offer:

Gúriestel or Gúriesteth (f. heart-wish)

That's interesting. I had first chosen Nauthira or perhaps Nauthiriel, but I wonder that I didn't land on that instead. Thank you very much!
