Ok, time to reveal the answer. Most of you were close or got the necklace correct, while the earring guesses seemed to vary. Both were purchased from PearlParadise.
Earrings are 7-8mm Freshadamas, white with rose overtones:
Necklace is 8-9mm FW AAA, white (no option to choose overtones):
You can see here that there are slight variations in roundness from pearl-to-pearl when it's very up close (don't mix it up with the uneven lighting off the pearl reflections from my makeshift lighting setup).
A few of you actually graded the earrings lower than the strand. That might be due to my photography - I had trouble getting a sharp focus on the earrings. But I have to admit, in person, I also think the necklace was more impressive. Maybe it's the more apparent pink inner glow (not sure what that's called) or the fact that there are just more of them clustered together.
