Sorry can't help you but these are beautiful earring & I'd love to have a pair too.
If you estate jeweller is reputable they should have an appraisal from a third party appraiser & be able to give that to you. If they don't have a third party appraisal you can ask that one be included in the purchase price. It has to be from a third party appraiser not from your jeweller. You will need one for insurance purposes & it is reasonable to ask that it be provided.
DH just asked what I was doing so I showed him your photo and he said he likes them & are they for sale.
He has great taste in Tiffany jewellery.
Good luck!
