Fabulous Paperweight in the form of teardrop mushroom. Mid century modern glass sculpture or paperweight designed by Ann & Goran Warff for Kosta of Sweden. The paperweight is fully marked on the bottom, as shown, “Kosta 97324 Warff. It is one of a series of “Bubble Sculpture” paperweights, with a clear ‘mushroom’ cap over a bubble base. This model, #97324 is quite rare, having a pointed or teardrop shaped cap. The code dates this piece to the early / mid-1970s, after the 5-digit code was established but before the name was changed in 1976 to Kosta Boda. 114.3mm x 69.8mm Weight is 762grams I can see two tiny littl pinhead marks but feel these are part of manufacture. Also a funny almost what looks like an impact mark inside the glass at the base but also could have been at time of manufacture. Only stating these things for accuracy.
