Hi Anna,
Wowee! That is some necklace. Very expensive.
You have clearly defined taste and I don't know if you like vintage so you may not like the link above. Ruby Lane is a site that often has more higher quality vintage jewelry pieces than Etsy. I have zero connection with them but a friend who does wardrobe for TV shows swears by them.
I put in the term "runway necklace" in the vintage jewelry category and came up with some fun sparklers.
