Requesting help identifying pattern/maker/name of destroyed set

Looking for help identifying this crystal/glass set if possible. My mother sent them USPS and they were all destroyed and to make an insurance claim they require proof of value. These were handed down from my great grandmother so not so easy finding replacements or to show value. I'm not even able to find the pattern to find similar items. I don't claim that they are actually valuable or anything but just need to find proof they are valued at least up to the $100 insurance coverage to make the actual claim. Of course, being family heirlooms they have much more than any monetary value but USPS seems to have their system setup to make sure they rarely have to pay out anything even if they completely destroy packages well marked "fragile".

Any help would be appreciated.
