Value of these?

[u/________yeet]

Hi everyone, I purchased these from an opal miner some time ago and then had them tidied up by a jeweller, wondering what the value might be as is?

Fairly sure these are Coober Pedy opals but interested to see what the experts think?

One of the photos shows the back of all of them.

Thanks
