Unmarked turquoise glass trivets (hobnail, Jadeite)

I think these are "Jade" glass.

Cheers. There's Fire King Jadeite by Anchor Hocking but not matching the bobbles (nobnails) on the top

Looks like a copy of Iittala Kastelhelmi. I say copy as I've never seen it in this opaque jade colour. It's usually transparent. There's been quite a lot of scandi influenced designs sold in homestores over the past few years

Cheers. Now I realise why it looks familiar :)
