Viking art glass green apple paperweight

I believe this to be a Viking glass item. I recently acquired a bit of Viking glass from a recent estate and also checked this against other Viking apples on-line and they are exactly the same. No chips, hairlines or cracks noted. I see listings are calling this a paperweight, but it is hollow. It is very decorative and quite attractive. Keep in mind all the upcoming teacher gifts when school starts again! Apple is 4 1/2" in height to tip of stem and about 3" across. The sides are indented to resemble a "green delicious" type apple.
