Totally no interest in gold, but I think she prefers gems as she prefers pieces with sapphires and diamonds.
My missus saw the flower bracelet and loved it, reckon if you were to melt it she might give you a good slap around the ear.
Baby jewellery is generally all 22ct or 24ct, the 24ct stuff can still have 18ct - 22ct joins / clasps etc. for functionality I was told this is because their skin is still sensitive so at 22ct+ your talking only around 8% other alloys, people that have skin reactions (not yet known on a baby) with low ct Gold it's actually the Copper etc they are reacting with not the Gold. Hence why baby Jewellery is high ct Gold.
