A pair of engine-turned gold opera glasses, scattered with diamonds and ringed with pearls at both the looking and viewing ends of each glass, the central hinge with a diamond-set octagonal twister and pearl finial.

Tiffany & Co. were well known for their production of luxury items but opera glasses of gold were rare - usually the surfaces were mother of pearl or enamel, in imitation of eighteenth-century pieces. Here the firm have used engine-turning to create a decorative surface to the gold, which has been adorned with rose-cut diamonds.
