Hi, it's probably Calcite, but where was it found and was it found ;in situ' or loose? can  you scratch it with a 'copper' coin?

If it's associated with fossils it's probably calcite.
Cheers

Could be quartz, calcite, may be baryte...

If you can't scratch it with a steel knife, it's quartz. If you drip some acid onto it and it fizzes, it's calcite. If it feels very heavy for its size, baryte.

It was found in Swanage, Dorset. Also known as the Jurassic coast. There are a lot of rocks lying there with white crystals in it. This one was the most extraordinary one so i brought it home.
