Set of Victorian style mantle lustres top condition

A pair of Victorian style mantle lustres, possibly of Bohemian origin, measuring 15 inches by 7 inches. 
The vessels are crafted from pale pink opaline glass with a subtle milky, swirled quality. Each piece comprises a tulip-shaped bowl with a deeply scalloped wafer rim, embellished with a thick band of gold gilding. The surface is hand-painted with enamelled floral sprays depicting orange-red blossoms on brown leafy stems. 
A central gilded collar on each piece supports eight clear, faceted glass rectangular prisms, suspended via wire loops. The lustres are supported by tapered, waisted stems that flare out into wide, domed circular feet, featuring matching hand-painted floral motifs and gilded banding. No maker's marks, signatures, or labels were found on either piece.
