Cut Crystal Azure Blue Inkwell

This is a striking example of 19th-century luxury glassware. The vibrant color and architectural “block” style make it a standout piece.

Color Description & Composition

The color is a brilliant Azure, but in the context of period-accurate French glass, it is most often described as Bleu Céleste (Sky Blue).

• How it was achieved: This specific shade of luminous, medium-bright blue was typically achieved using copper oxide (cupric oxide). Unlike the deep, moody royal blue produced by cobalt, copper oxide results in a range of sky-blue and aqua tones.
• The Crystal Factor: The “glow” achieved suggests a high lead content. Lead crystal refracts light more brilliantly than standard soda-lime glass, which makes the blue appear “electric” rather than flat.

The Cut & Design

• The Base: This is a faceted block cut (sometimes called a “grid cut” or “cross-beveled”). The deep vertical and horizontal grooves create a structural, prismatic effect that maximizes internal reflection.
• The Lid: The lid features a jewel-faceted or prismatic cut. It has a large central “table” facet surrounded by a perimeter of smaller trapezoidal facets, designed to mimic a large-cut gemstone.
• The Fittings: The brass collar is notable for its beaded or dotted border. This “beaded gallery” style was a hallmark of high-end French desk accessories.

Estimated Age & Origin

• Origin: Likely France. This style is quintessentially Napoleon III or early Belle Époque.
• Estimated Age: Circa 1870–1900.
• Potential Maker: While often unmarked, the quality and specific beading on the brass are highly characteristic of Baccarat or the Cristallerie de Saint-Louis. These prestigious houses frequently produced “bollard-shaped” or square-block crystal inkwells with gilt-bronze or brass fittings during the late 19th century.
