Need ID on something that burned my finger

This is a weird one.....

Today I noticed this tiny, very blue, pebble sized, thing on my sand bed. I figured either my kids got something in the tank or came with the sand and I was just seeing it. I used a long pair of tweezers to get it out and then grabbed it between my thumb and forefinger at Wich point the blue color stained my fingers and it started to burn almost immediately. I dropped it and went to wash my hand and it the burning went away after a few minutes but I can't for the life of me figure out what it is. It's really small, the blue color rubs off really easy, and it's got some hair and crap stuck to it from being in the floor as you can see.

Anyone want to guess ?

Interesting. Any chance you can put it in a small amount of rodi water then check the pH of the water? I'm assuming the burn feeling would have been from a chemical burn rather than a temp but not sure if it's acidic or basic. rodi should have a pH close to 7.00 so deviations from that would help differentiate.

Have you been using potassium permanganate?
