A French 19th-century opaline glass casket in a rare periwinkle blue tone, with subtle violet undertones. The shaped form is fitted with gilt bronze mounts, including a hinged lid and decorative clasp.
Boxes of this type were prized in the 19th century as luxury objects, admired for their luminous color and elegant proportions. The periwinkle hue is less commonly found than the classic sky or lapis blue opaline, making this example especially desirable for collectors of fine decorative glass.
