Coffee and Side Table ?

They where advertised as stone on Furniture 123 where I got them but I think they are plaster so not to heavy. I loved these and got so many compliments on them over the years but they are not child friendly so I need to replace them. I paid over 400 for them new. There are scratches to the glass as you would expect with use. Coffee Table 65 Side Table 45 or 100 for the pair
