I found this amazing sphere in an oddball shop the other day, and the shop owner and I were guessing it may be Rhodochrosite or Rhodonite.
It looks more brown in the photo than it truly is - it's actually pink.

What stone is it?

It looks, to me, like nothing so much as polished Mookaite, that is agatised coral, mostly found in Australia, the various lines through it are actually coral growth-rings fossilised by silica saturated ground water.

    $\begingroup$ I ended up taking it into a rock and crystal shop I know and trust and the owner said "mookaite"! I didn't even have to suggest it. So thank you all so much! $\endgroup$ – Jennafer Marie May 30 '18 at 17:20
  • $\begingroup$ @JennaferMarie No worries, the little pieces most places sell are really brightly coloured but I've got large cut pieces that show the inner structure so it was easy for me to see it for what it was. $\endgroup$ – Ash May 30 '18 at 17:26

That is most likely cornelian which is flesh or red-brown type of chalcedony. That looks like the colored variety which exhibits strips. Can't tell from picture but if color distrabution is cloudy then its the natural variety.
