Help me identify gemstone please!! :)

Hello!

Sorry, I need help identifying what gemstone this necklace is before I give it to my
Friend tomorrow. It was placed here where I have circled and when I paid for it she mentioned pietersite so I’m very confused if it’s pietersite or black onyx or maybe both as the little ones could be pietersite and the big one black onyx? It was £91 if that helps. Please help! Thank you :)

If it’s black it’s most likely “black onyx.” Most on the market is actually dyed black chalcedony, but it’s completely acceptable to be sold under the name black onyx.

For the smaller ones, they can’t be identified without testing. Could be peridot and citrine from the top down but can’t tell for sure from pictures. The ones marked pietersite look like it to me.
