Handmade/mouth blown drop vase, Finland or Sweden 1970s

Very beautiful handmade/mouth blown drop vase in blue and purple glass. You can see on the bottom that it is mouth blown (where it is broken off on the glass blower's stick) It is so delicious oh with cool details like the blue color that starts at the bottom and as we approach the top turns into a purple color. It is either Swedish or Finnish and from the 1970-80s. No chips, cracks or other defects. It is 22 cm in height, 11 cm in diameter and weighs about 755 grams. Will be packaged securely and shipped with insurance.
