Vintage Caithness Glass "Harlequin Double" art glass paperweight designed by Paul Ysart.

It features scattered millefiori canes and small shells on the base with internal air bubbles (stamens) rising through green glass.

The signature cane clearly shows a stylized "CG", which officially stands for Caithness Glass and links the design lineage directly back to influential glassmaker Paul Ysart's era

This paperweight is in very good condition.
