A chalcedony double fish snuff bottle, 1820-1880. Photo Bonhams.

Formed as two fish joined at the belly, with flat lips around their mouths, their curved tails overlapping, with the individual scales delineated, the interiors very well-hollowed. 2 1/4in (5.8cm) high. Sold for US$ 2,375 (€1,707)

For a very similar example, see Hughes, The Blair Bequest, Chinese Snuff Bottles From the Princeton University Art Museum, Baltimore, 2002 no 46, where the author notes that while double fish bottles are not uncommon, the form in chalcedony is relatively rare.
