This is a lovely Scottish paperweight. It is engraved Caithness Scotland MAY on the base and N68558. It comes from the Floral Year / Flowers of the Month series.
It is certainly a pretty little weight and a slightly harder to find one.
This one has a dark inky-blue ground with a single lampwork flower in the center - around the edge is a pretty border of millefiori canes. The little white flower has four bell-shaped flower heads. And two broad leaves at the base of the stem.
It is in excellent condition with no damages. Dimensions: Diameter is 6.5 cm and the height is 5.5 cm
