" help i have a collection from my dad he was a driller in the north mine broken hill and need help to identify some pieces thanks"
You should use a different title for each specimen, it's hard to find each one otherwise.

Are you able to post a photo looking down at the top of the crystal? I think the large crystal is probably calcite, but would help to see another angle.
The small colorless crystals on the side are interesting. Those don't look like calcite to me, but no idea what they are.
