Helena Tynell - Emma

I hope you can help me, sorry I do not speak Finnish, but I know many of you will speak and understand English without problem. I have an Emma bottle, that came with a square decanter stopper, the glass seems the same colour, but has a texture to it that seems more in keeping with an Italian Empoli decanter, rather than a Riihimaen one. Does the Emma bottle come with a stopper, or has the original owner simply matched it up with one? Many thanks, Lynne
