Need assistance

I was in my house that is 27km from spawn and I just finished making the whole set of gem armor for the first time.
I was using the crafting table to make another swiftwolf ring and i died. It said sunnyjim99 blew up.
I had full life, and my full set of gem armor on and died instantly.

I did /home right after i died and warped back to the exact spot i was standing in at death. None of my stuff was there.

Dc came to check it out and without too many words teleported away to help someone who got griefed.
Later i asked gnarkill to help and he said he cant unless it was griefing.

It wasn't griefing but now I am without any of my stuff which literally took me a few days to craft.
If it can't be helped, it can't be helped, but I would like to try and get some of my stuff back.
