For some reason the internet seems completely silent when it comes to the existence of iridium shards. Considering how easy it seems to be to find them and how hard it is to find iridium, I don't understand this, unless they're completely useless.
I am using MC version 1.7.10 and IC2 2.2.817
Here's a screenshot of the object I'm referencing. It looks kinda like a gray sharktooth and is labelled Iridium Shard, not ore.
