Elegant Daum Nancy cabinet vase in multi-layer (cameo) glass, with a classic vine & grape décor acid-etched in relief and subtly enamelled (red/green/violet nuances) over a marbled yellow-amber ground.  The surface has a distinctive frosted, granular (“fond givré”) finish, a deliberate matte effect from the acid treatment, which can look slightly “sandy” under the light.  Signed in the décor with the acid-etched “Daum Nancy” mark (Cross of Lorraine).  This signature style (without “France”) is consistent with production before 1924, supporting an early 20th-century / circa 1900 dating for this model.
