They were self-collected, but I don't know what they are or where they are from.

Geologically is it a double terminated, twinned quartz crystal(pic 1 & 4). However, if you are a Star Trek fan they are dilithium crystals. They used Quartz Crystals on the show for dilithium.

Those are great, you should see if anyone else in the family knows where he may have collected them from. If there are any local rock/mineral clubs nearby you can see if they recognize it or maybe even if they knew your Grandfather, that is assuming he is no long with us.

Wow howgneiss - I was literally just about to create a post asking about some similar quartz crystals that I have. I don't have too many double terminated ones - most of mine are flowers, I guess. When I do an internet search for Pecos Diamonds, some like yours and mine come up!

It's interesting how they form so differently.
