Once upon a time I took apart and sorted some strands of old quartz beads from Mali, and found a couple pieces with a similar creamy pink layer combined with a more carnelian layer - such as displayed around the tiny patches of druse (tiny crystals) and fortification agate in your picture.
The yummy pink coloring is possibly from microscopic hematite?

It's such a nicely shaped and polished bead, I don't think it came from Africa, however.

There's a porcelain-like pink jasper as well - Imperial Jasper, I think is it's trade name - but I don't recall seeing those little carnelian and druse patches in it. It's more like pink Bruneau Jasper.

At any rate, some kinda quartz...
