Perthshire Paperweights Ltd. (often simply referred to as “Perthshire”) was a Scottish glass studio, established in 1968 in Crieff, Perthshire, Scotland.

It was founded by Stuart Drysdale and a team of skilled glassworkers who had previously worked at Strathearn Glass including John Deacons, Peter McDougall and Jack Allan, who apprenticed with Salvador Ysart. The company’s motivation was to produce high-quality millefiori and lampwork paperweights in the tradition of the great French firms, but with a Scottish setting and sensibility.

During the lifespan of the company (1968–2002), Perthshire became known for its annual limited-edition collections, distinctive signature marks (most commonly a “P” cane or engraved “P”), and a variety of designs including floral motifs, close-packed canes, and special commemorative editions.

While the company was relatively small, its output was consistent in quality and remains extremely collectible today.  Ultimately, economic pressures led Perthshire to cease production in early 2002 after more than three decades of operation.
