Can someone help me identify

[Flyinhawaiian]

found these in a jewelry box in my moms old place.
They are 5.7mm
The lever back clasp are 14kt yellow gold

They are blue with pink hues and other colors, at certain angles is looks darker. sorry I’m not very familiar with all this.
But if anyone could help I’d greatly appreciate it

Are those natural light photos? If not could you try to take some in lighting that shows the pink overtone hues?
Generally overtones are best seen in diffuse light-- indoors, or outdoors in the shade or on an overcast day.
I'm wondering if they may be naturally colored akoyas, which can look silvery blue and can have pink overtones.

Honestly I'm not sure from the photos. but they could be naturally colored akoyas. Or they could be dyed akoyas.
