[simo444r]

Sorry if this is the wrong place to ask. i recieved these from my grandad recently and he said that they are rubys. im not really sure what they are and if they are what should i do with them.

It might be corundum, but most definitely not ruby

They could be Pyrope

Whatever it is, it's not gem grade material and it is not valuable.
