Paperweight, Kosta Boda, Mona Morales-Schildt

Small paperweight, signed "Kosta SH 5830"
It's approx. 93mm in hight.
Unfortunately there are two visible damages to one of its sides (they can't really be felt) but I love it nonetheless. It doesn't look too "busy" and yet has something very special about it.
Love how the little clear "window" in the middle matches perfectly with the bubble on one side (the damaged one is slightly off)
Why it was sold as "Holmegaard" I will probably never understand ;)

I couldn't find if this has a special name or how old it is so any additional information is appreciated.
