It is hard to tell from the pics shown, but I reckon if it's pink all the way to the top, it's more likely to be IoWSG Summer Fruits than Iestyn Davies' version of something very, very similar at Stuart Strathearn - Impressions, (which he did following his time at IoWSG), which tends to have a lot of white in it.
Stuart Strathearn is more connected to Ysart Glass and it's heritage than it is to Stuart Crystal, really.
Perhaps not financially, but certainly in design.
