Navette — The French Term for the Marquise Cut
Navette — The French Term for the Marquise Cut
The pointed-oval brilliant cut, used interchangeably with marquise in European trade and antique jewellery
Navette is the French trade term for the marquise cut — the elongated, pointed-oval brilliant cut whose outline tapers to two sharp points along the long axis. The word derives from the French navette, meaning "little ship" or "shuttle," describing the silhouette's resemblance to a weaver's shuttle or the hull of a small boat. The term is used interchangeably with marquise in European trade and antique-jewellery contexts, with navette being more common in French and Continental usage and marquise dominant in English-language usage. Older English-language jewellery literature, particularly nineteenth- and early-twentieth-century catalogues, frequently uses navette as the principal term.
The cut
The standard navette/marquise cut is a brilliant-style cut with 56 facets in the configuration developed for the round brilliant and adapted to the elongated outline. The crown carries a kite-shaped table, four kite-shaped bezel facets, and eight star facets and sixteen upper girdle facets in the standard arrangement. The pavilion carries eight pavilion mains, sixteen lower girdle facets, and an extended culet line that may either come to a point or be polished to a small culet ridge. The proportions — length-to-width ratio, depth percentage, table size — are evaluated similarly to round brilliants, with the ratio of length to width being the principal additional consideration unique to the cut.
Common length-to-width ratios for the navette cut range from approximately 1.75:1 to 2.25:1, with 1.85:1 to 2.00:1 considered the classic and most desirable proportions. Lower ratios produce a stockier outline that overlaps with the oval cut; higher ratios produce a longer, narrower silhouette that emphasises the shuttle shape but may show pronounced bow-tie and other optical issues.
The bow-tie effect
One optical issue specific to the navette cut is the bow-tie effect: a darker zone running across the centre of the stone where light is not returned to the viewer's eye. The effect derives from the cut's geometry, where the pavilion facets in the central section of an elongated stone direct light away from the table at angles that reduce face-up brilliance. A pronounced bow-tie is a defect; a faint or barely visible bow-tie is acceptable in most commercial work and unavoidable in some proportion of marquise cuts. The cutter's skill is judged in significant part by how well the bow-tie has been minimised in the finished stone, and high-grade marquise cuts may achieve a near-invisible bow-tie at the expense of slight weight loss compared with a less optimised cut from the same rough.
Origin and the Pompadour story
The traditional account of the marquise cut's origin attributes the design to Louis XV of France, who is said to have commissioned a diamond cut to resemble the lips of his mistress Madame de Pompadour, with the cut named the marquise in her honour. The story is part of the cultural legend rather than the documented history; period records do not confirm the specific commission, and the elongated pointed-oval cut form has antecedents in earlier seventeenth-century cutting practice. The story is worth knowing as part of the cultural narrative around the cut, but should not be cited as documented fact in catalogue copy.
Use in jewellery
The navette/marquise cut is popular in solitaire rings, three-stone rings, and as side stones in fancy-shape rings. In ring settings, the long axis of the stone is typically aligned along the finger, producing an elongating optical effect that many wearers find flattering. The cut is also used extensively in earrings (pavé-set drops, chandelier configurations) and in bracelets, where multiple navette stones can be set end-to-end or in alternating patterns with rounds and other shapes.
Setting considerations include the protection of the two pointed tips, which are the most vulnerable parts of the stone and the most likely to chip in routine wear. V-prong settings — prongs shaped to fit and protect the points — are the standard approach. Bezel settings provide more comprehensive protection at the cost of some apparent stone size and brilliance.
Eighteenth- and nineteenth-century work
Antique navette-cut diamonds and gemstones from the eighteenth and nineteenth centuries are encountered regularly in period jewellery contexts. The proportions and cutting practices of period navette stones differ from contemporary work: older stones often show steeper crown angles, larger culets, and less optimised bow-tie management than current cutting. The deeper crowns and larger culets give period navette stones a distinctive optical character — the older stones often show more dispersed flashes of colour and less bright white light return than modern cuts, in line with the broader characteristics of old mine and old European cuts. The character is part of the appeal in period-jewellery contexts and should not be treated as a defect when found in pieces of the period.
The term in catalogue and report copy
The trade convention is that navette and marquise are interchangeable, with regional preference determining usage. GIA grading reports and other major laboratory documents use marquise as the primary term. European and antique-jewellery catalogue copy, particularly French and Italian, use navette more frequently. The two terms describe the same cut and are not used to distinguish particular subtypes, although some idiosyncratic dealer usage has reserved navette for older or more elongated examples.
