Also saying OPs daughter has other pieces means nothing... when I was a teen my mam and dad (and they encouraged others too aswell) both went through this phase of buying me 'expensinve' jewellery... I have never wore any of it once.
The diamond set has sat in my mams safe for 18 years without me even having access to it because it needs to be 'protected', the solid silver stuff thick chunky chains and massive pendents my dad bought is so horrifically dated to the 00s no one would wear it and the stuff family bought where such misses for my taste (what teen wants giant dress granny pearls).
If you asked them though they all thought if was 'fantastic' and the pwefect gift for a teen though, my mam kept saying I would wear this stuff on my wedding day and it would be heirlooms etc... I did not wear it on my wedding day (I bough a pretty dainty opal set of etsy for my wedding, not chunky silver & white gold and diamands and massive pearls that family kept giving me) and have zero urge to pass it on as heirlooms.
If OPs daughter had asked for this she wouldnt be asking us so clearly this is an idea she came up with not a longing of the daughters.
