Here is a crystal bowl by Gunnar Cyren of Orrefors. Bottom reads "Orrefors 998672 Gunnar Cyren EAJ - 93" I believe. And is signed again simply "Cyren" in the center of the bowl underneath. The colors very between blue and purple with these white lines and dots, its an asymmetrical centerpiece bowl. It measures 13"W and about 10.5" T. Purchased at the artist's studio in Stockholm, not sure of the date but likely late 20th century. Not very heavy, considering its size. It is very reflective and you can see the design from inside and outside of the bowl.
