This is certainly a very stylish paperweight to add to your collection.
It was made by the glass maestro at Caithness Glass, Colin Terris (1937 - 2006).
This is a more minimalistic space-age design called PULSAR (CT-957).
It is number 521 out of a limited edition of just 750 pieces (closed at No. 612).
The weight has a rich bright Royal blue ground sprinkled with tiny controlled bubbles - there is a larger clean silvery bubble on the ground center. Floating above is a space cloud made of lots of tiny granular speckles. In the very center of the weight is a very large floating air bubble.
It is of course in excellent condition with no damages.
The weight measures 2 3/4 inches in height with a diameter of 3 inches.
The weight unpacked is 625 grams.
It will cost £4.95 to send to the UK with Royal Mail Recorded. This will be applied at the checkout stage.
