Baguette Cut Moissanite: more face for its weight than a round, and lighter than diamond

Brilliance 32 · Fire 75 · Scintillation 43 · in our census, where the T73 scores 86 · 97 · 80 in moissanite

A slim step cut with only 21 facets: in moissanite it weighs less than a diamond baguette and shows a little more face for its weight than a round, while returning far less light.

Baguette Cut Moissanite

Ours stretches 1.974 widths long and carries just 21 step facets over a 32.37° pavilion, 66.8% deep. Jewelers set baguettes beside a bigger centre stone, or end to end along a channel-set band.

Its two pros are about size and weight; its four cons are about light and pattern. On symmetry it is the lowest cut we measure, and on leakage only DG-Elongated Hexagon loses more in moissanite.

Even fire, where moissanite usually shines, is low here: 75, the lowest of any cut we measure in moissanite, though still above the diamond baguette's 62.

Is a baguette cut good for moissanite? Pros and cons

Compared with the T73 Round Brilliant in moissanite and with the Baguette Cut in diamond. A difference counts from 3 points (Brilliance, Fire, Tilt, Leakage), 5 (Scintillation, Symmetry), 4% (face-up size per carat) or 5% (weight); Tilt counts as a pro only for a stone within 5 points of the brilliance it is compared with. How we measure.

What moissanite gains in a baguette cut

Lighter than a diamond baguette

3.33 ct at 6.5 mm, against 3.64 ct for the same cut in diamond (−9%)

A baguette 6.5 mm wide is a long stone, and a heavy one for its width. Moissanite's specific gravity of 3.22, against diamond's 3.52, trims the carat figure for the same millimetres.

A little more face for its weight than a round

Face-up size 108 against 100 for the T73 Round Brilliant in moissanite (T73 = 100): 8% more face-up area for the same weight

Face-up size compares a model's outline area with its weight, with the T73 at 100. Weight for weight, the baguette's outline covers 108 to the round's 100: a modest gain for a stone 66.8% deep.

Baguette Cut · 8.61 x 4.36 mm at 1.00 ct · Face-up size 108

T73 Round Brilliant · 6.68 mm at 1.00 ct · Face-up size 100

Both stones weigh 1.00 ct in moissanite and are drawn to the same scale in millimetres, from each cut's own model. Face-up size is the outline's area per carat, with the T73 at 100: a deeper stone, or a rounder outline, spreads less area for its weight.

The catch with a baguette moissanite

The least regular pavilion we measure

Symmetry 39 against 100 for the T73 Round Brilliant in moissanite: 61 points lower

Symmetry scores how evenly a design's pavilion facets repeat. The baguette's 39 is the lowest of all the cuts we measure, while the Rectangle, a step cut with square corners, scores 100.

Baguette Cut · 21 facets · Symmetry 39

T73 Round Brilliant · 73 facets · Symmetry 100

Symmetry scores how regular the pavilion facets are within the design. Compare how evenly the facets repeat around each pavilion. Drawn from each cut's own model.

What helps: For a step-cut rectangle with a fully regular pavilion, the Rectangle scores 100.

Far less light than a round

Brilliance 32 against 86 for the T73 Round Brilliant in moissanite: 54 points lower

Brilliance 32: only DG-Bowtie and DG-Elongated Hexagon return less in moissanite. Its 32.37° pavilion sits well under the 39.5° guide minimum, but that guide is drawn for round designs, and we have not measured a steeper baguette.

T73 Round Brilliant in moissanite · Brilliance 86

Red, green and blue = light returning to the eye; grey = light leaving through the pavilion. This is the head-on view; the Brilliance score averages a wider cone of light, so the score can differ from what one picture shows.

What helps: No long step cut we measure gets near a round: the Emerald Cut returns 51. For the most light in moissanite, DG-M5 Moissanite at 98.

Few flashes as it moves

Scintillation 43 against 80 for the T73 Round Brilliant in moissanite: 37 points lower

Our scintillation score is read from the facet pattern, so a baguette earns the same figure in any gemstone. With 21 facets it gives little of it; among the cuts we measure, only the Triangle scores lower.

Baguette Cut · 21 facets · Scintillation 43

T73 Round Brilliant · 73 facets · Scintillation 80

Scintillation follows the number of facets: more facets, more and smaller flashes as the stone moves. Count the facets in each crown. Drawn from each cut's own model.

What helps: 21 facets cannot flash like 73, whatever the angles. The Emerald Cut keeps a long stepped look with 72 for scintillation.

Over two fifths of the light leaks

Leakage 42 against 7 for the T73 Round Brilliant in moissanite: 35 points higher

42% of the light in our census leaves through the back, many times the T73's 7%. The diamond baguette loses 38%, so moissanite does not rescue it.

Each frame is the Light Return map with the stone tilted away from you by the angle shown; grey is light leaving through the pavilion. The share under each frame is that picture's own.

What helps: Leak share holds at any size. The Rectangle leaks 29%, DG-Anteros Moissanite 3%.

Where a baguette moissanite belongs

The baguette suits side stones and channel-set bands, where straight lines and a small size matter more than the light a stone returns. There moissanite gives it less weight than diamond and a little more face for its carats.

As a centre stone it is a weak pairing, with little light and few flashes. For a long step-cut outline with more of both, the Emerald Cut; for a bright centre stone, a round such as DG-Anteros Moissanite.

Moissanite is doubly refractive, and a baguette's long steps are where doubled facet edges would show. We trace one refractive index, so we cannot say how much.

Baguette Cut Moissanite: questions

Is baguette cut moissanite sparkly?

Not much. Scintillation is 43 against 80 for the T73 Round Brilliant, and Brilliance 32 against 86: it is a cut of clean lines rather than glitter.

How much does a 6.5 mm wide baguette moissanite weigh?

3.33 ct in moissanite and 3.64 ct in diamond. Our model is 1.974 times as long as it is wide, so that is a long stone.

Baguette or emerald cut moissanite?

The emerald cut returns more light (51 against 32), shows more fire (95 against 75) and leaks less (27% against 42%).

Do moissanite baguettes leak light?

This one does: 42% in our census, where the T73 Round Brilliant loses 7% and a diamond baguette 38%.
