This is certainly a very beautiful paperweight to add to your collection.
It was made in 1992 by the glass maestro at Caithness Glass, Colin Terris (1937 - 2006). This one is called Hydrophonic and is CT-872. It is number 612 out of a limited edition of just 750 pieces. It was a popular design and fully subscribed.
This is another lovely weight by Terris. It has a bright clear emerald green ground. It has a border of little single air bubbles around the outer edge of the ground. In the centre is a large flattened, round air bubble from which rises a pink flowerhead - with another large pearl-like air bubble in the middle.
Dimensions: it is 3 inches in diameter and 2 3/4 inches height. Unpacked it is 630 grams. It is of course in excellent condition with no damages.
