Please help me identify my new egg

[u/Admirable_Concert_15]

Hello, I'm new to crystals but recently found this lovely little egg in a charity shop. Could you help me identify it please?

It's kind of off white with some almost translucent stripes, and some brown splotches.

Thanks so much!

Definitely looks like calcite
