What's this Stone?

[Mikasseh]

I found a stone in our backyard that was form of an animal. Due to my curiousity i broke it. And surprisingly i found something strange inside of it. A dash of mini stones that sparkles even at night. My parents told me it's a diamond. But i still confused if its real diamonds. We dont have any tester to make it proof that it was. And based on historical events in our place. Our land was formerly camped by the japanese military during the WWII. Please help me to figure out this strange object i had. If ur interesting just check my albums. For the pictures.

Pretty hard to ID rocks from just a picture, but you might have something.
