if its soft white chalk like rock it is aragonite, if it is hard and grey/multi-tone it is likely lace rock.

It's aragonite then. I cracked some large pieces to get smaller ones and it's white inside and clearly soft enough to break along good lines. I'll bring some of my extra rock to swap on the 10th if that's cool with you.
