Help finding an SCP?

It’s two rings. One who wears a ring cannot stay more than 10 feet(?) apart from the other wearing the matching ring without degenerating rapidly and dying. I remember reading the whole thing, it was very creative and in a journal format. I’ve been trying to find this SCP for a long time now, but just like the shop that sold the rings, its number has completely dissolved from my mind. I think it was around the 4000 mark, but I might be way off.
