This fine paperweight was made by the glass maestro at Caithness Glass by Margot Thomson. This one is called Chrysalis and is CT-800. It is number 50 from a limited edition of just 750 pieces (closed at 718).
It has the etched edition number and title on the base.
This lovely weight has a crystal clear main body colour with controlled air bubbles in the center and an emerald green tint to this area - there is a flat circular faceted viewing window to the front.
It is of course in excellent vintage condition with no damages - and measures 3 inches in height, so a nice larger sized weight.
