Light Return map of the Marquise Cut in chrysoberyl, face-up, from our own tracer at refractive index 1.746. Red, green and blue return light to the eye; gray leaks.

## Marquise Cut Chrysoberyl

Chrysoberyl has a refractive index of 1.746 to 1.755 and a dispersion of 0.015. Its critical angle, from the low end of that range, is 34.9°, so a round design needs a pavilion of at least 36.3° for head-on light to reflect off both sides of the pavilion and leave through the table. We trace it with one index, 1.751, the midpoint of the published range, and a fire spread of 0.013, 0.86 of the published dispersion. Every picture here is our Light Return tracer at 1.746, and every figure is from the same light census that scores the other gemstones; the 3D Gemstone Simulator shows the Marquise Cut in chrysoberyl live.

The Marquise Cut has 87 facets and a total depth of 62.0% of its width; its pavilion mains sit at 31.4°. In chrysoberyl, the census returns 54 of 100 for brilliance and 51 for fire, against 94 and 29 for the T73, our benchmark, in the same stone; the same Marquise Cut in diamond reads 64 and 89.

Compared with the T73 Round Brilliant in chrysoberyl and with the Marquise 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](https://digitalgemology.com/about/how-we-measure).

## All eight scores against the T73

At a glance: the Marquise Cut in chrysoberyl (white) against the T73 Round Brilliant in chrysoberyl (dashed): solid white where it reaches further, hatched where it falls short. Each pro and con is explained, with pictures, below.

Against the T73 Round Brilliant in chrysoberyl: ahead on 2, level on 1, behind on 5.

- Global 61, the comparison 77, difference −16
- Brilliance 54, the comparison 94, difference −40
- Fire 51, the comparison 29, difference +22
- Scintillation 86, the comparison 80, difference +6

- Symmetry 94, the comparison 100, difference −6
- Shape-norm 63, the comparison 101, difference −38
- Tilt 55, the comparison 75, difference −20

Face-up light census, a different measure from the Cut Grading Tool; Spread and Shape-norm above 100 sit on the ring. Spread is the census's estimate from depth alone; the face-up size in the pros and cons is measured from each model's outline. [Open it in the Cut Performance Wheel](https://digitalgemology.com/tools/cut-performance-wheel?cut=marquise&stone=chrysoberyl); these are the same census figures as our [Cut Performance Index](https://digitalgemology.com/learn/cut-performance-index).

## What the Marquise Cut gains in chrysoberyl

### Faces up larger for its weight

**Face-up size 121** against 100 for the T73 Round Brilliant in chrysoberyl (T73 = 100): 21% more face-up area for the same weight

Face-up size is the outline's area per carat, measured from each model (T73 = 100): 121 for the Marquise Cut against 100 for the T73. The same volume spread over a longer or shallower outline shows more face for the weight; it is the same in every stone, because specific gravity scales every cut alike.

*Face-up outline of the Marquise Cut at 1.00 ct in chrysoberyl: 10.28 x 4.99 mm, drawn to scale*

Marquise Cut · 10.28 x 4.99 mm at 1.00 ct · Face-up size 121

*Face-up outline of the T73 Round Brilliant at 1.00 ct in chrysoberyl: 6.36 mm, drawn to scale*

T73 Round Brilliant · 6.36 mm at 1.00 ct · Face-up size 100

Both stones weigh 1.00 ct in chrysoberyl and are drawn to the same scale in millimeters, 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.

[Try it yourself: See its size at 1.00 ct in chrysoberyl in the 3D Gemstone Simulator](https://digitalgemology.com/tools/3d_gemstone_simulator?cut=marquise&stone=chrysoberyl&ct=1.00&view=up&lighting=studio&turn=0)

### More facets, more sparkle

**Scintillation 86** against 80 for the T73 Round Brilliant in chrysoberyl: 6 points higher

Scintillation follows the number of facets the stone shows: 100 × (1 − e^(−facets / 45)). The Marquise Cut has 87 facets and the T73 73, so 86 against 80. It depends on the geometry alone, so it is the same in every stone.

*Facet diagram of the Marquise Cut: its crown, seen face-up, 87 facets in all*

Marquise Cut · 87 facets · Scintillation 86

*Facet diagram of the T73 Round Brilliant: its crown, seen face-up, 73 facets in all*

T73 Round Brilliant · 73 facets · Scintillation 80

Scintillation follows the number of facets: more facets, more and smaller flashes as the stone moves. Compare the facet counts under the drawings; each drawing shows only the crown. Drawn from each cut's own model.

## What the Marquise Cut gives up in chrysoberyl

### Returns less light than the T73 in chrysoberyl

**Brilliance 54** against 94 for the T73 Round Brilliant in chrysoberyl: 40 points lower

Brilliance is the share of the 3,200 census rays that enter the stone and come back out of the crown towards the viewer. In chrysoberyl, whose critical angle is 34.9°, the Marquise Cut returns 54 of 100 and the T73 94. The Marquise Cut's pavilion mains sit at 31.4°, the T73's at 40.8°. The maps below show where each stone's light returns from and where it leaks.

Marquise Cut in chrysoberyl · Brilliance 54

T73 Round Brilliant in chrysoberyl · Brilliance 94

Red, green and blue = light returning to the eye; gray = leakage, light that leaves heading down or stays inside. 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:** [the DG-M5](https://digitalgemology.com/gemstones/chrysoberyl/dg-m5) reads 100 for brilliance in chrysoberyl, the best of the cuts we score there.

[Try it yourself: Open this Light Return map in the simulator](https://digitalgemology.com/tools/3d_gemstone_simulator?cut=marquise&stone=chrysoberyl&ct=1.00&view=up&map=1&turn=0)

### Less fire in chrysoberyl than in diamond

**Fire 51** against 89 for the Marquise Cut in diamond: 38 points lower

Fire is the share of the returned light that splits into color at the exit facet: the census traces each exit again at the refractive index minus and plus the fire spread (0.013 in chrysoberyl) and counts a ray as fire when the two directions differ by more than 0.6°. The Marquise Cut reads 51 against 89 for the same cut in diamond. The figure is the census's; the 3D Gemstone Simulator renders chrysoberyl's fire live.

The fire figure is the census's, traced at the refractive index minus and plus the fire spread. [See the fire in the 3D Gemstone Simulator](https://digitalgemology.com/tools/3d_gemstone_simulator?cut=marquise&stone=chrysoberyl&ct=1.00&view=up&lighting=sun&turn=0): the Marquise Cut in chrysoberyl under the sunny-day lighting.

**What helps:** [the Oval Cut](https://digitalgemology.com/gemstones/chrysoberyl/oval) reads 67 for fire in chrysoberyl, the best of the cuts we score there.

[Try it yourself: See the fire in the 3D Gemstone Simulator](https://digitalgemology.com/tools/3d_gemstone_simulator?cut=marquise&stone=chrysoberyl&ct=1.00&view=up&lighting=sun&turn=0)

### Leaks more light than the T73 in chrysoberyl

**Leakage 40** against 5 for the T73 Round Brilliant in chrysoberyl: 35 points higher

Leakage is the share of the census rays that enter the stone and leave through the pavilion, or through the crown heading down. The Marquise Cut leaks 40% in chrysoberyl against 5% for the T73 in chrysoberyl. Grey in the maps below is leaking light; the share under each picture is that picture's own.

Marquise Cut in chrysoberyl · Leakage 40

### Loses more light when tilted than in diamond

**Tilt 55** against 87 for the Marquise Cut in diamond: 32 points lower

Tilt is how much of its face-up brilliance a stone keeps when the census tilts it 20° about its long axis, with 2,200 rays. The Marquise Cut keeps 55 against 87 for the same cut in diamond. The tilt strips below show the maps at 0°, 10°, 20° and 30°, with each picture's own leak share under it.

Marquise Cut in chrysoberyl · Tilt 55

0° · 39% leak

10° · 40% leak

20° · 53% leak

Marquise Cut in diamond · Tilt 87

0° · 17% leak

10° · 23% leak

20° · 26% leak

30° · 29% leak

Tilt is how much of its own face-up light a stone keeps when tilted. Each frame is the Light Return map with the stone tilted away from you by the angle shown; gray is leakage. The share under each frame is that picture's own.

**What helps:** [the DG-Miliano](https://digitalgemology.com/gemstones/chrysoberyl/dg-miliano) reads 83 for tilt in chrysoberyl, the best of the cuts we score there.

## Our verdict on the Marquise Cut in chrysoberyl

Pick the Marquise Cut in chrysoberyl for this: it faces up larger for its weight and has more facets to sparkle with. The catch: it returns less light than the T73, shows less fire than in diamond, leaks more light than the T73 and loses more light when tilted than in diamond.

If that catch matters more to you, [the DG-M5](https://digitalgemology.com/gemstones/chrysoberyl/dg-m5) reads 100 for brilliance in chrysoberyl, the best of the cuts we score there.

Every figure on this page is from our light census, traced at one refractive index: a simulation of the geometry, not a grading report. The 3D files and cutting files below are the same Marquise Cut model we traced.

## Marquise Cut Chrysoberyl: questions

### Is the Marquise a good cut for chrysoberyl?

In our census the Marquise Cut returns 54 of 100 for brilliance and 51 for fire in chrysoberyl, against 94 and 29 for the T73 in the same stone. Against that round and against the same cut in diamond it has 2 pros and 4 cons by our thresholds; the summary above names them.

### What pavilion angle does chrysoberyl need?

At least 36.3° for a round design: chrysoberyl's critical angle is 34.9°, from the low end of its refractive index range, and head-on light has to reflect off both sides of the pavilion and leave through the table. The Marquise Cut's pavilion mains sit at 31.4°.

### How much does a Marquise weigh in chrysoberyl?

At 6.5 mm across, 2.22 ct in chrysoberyl, against 2.09 ct for the same cut in diamond (+6%): chrysoberyl's specific gravity is 3.73, diamond's 3.52.

### Can I see the Marquise in chrysoberyl in 3D?

Yes: the 3D Gemstone Simulator renders it live, with chrysoberyl's own refractive index and dispersion. Chrysoberyl is traced by the same light census as the other gemstones, with its refractive index and fire spread derived from published values, so its scores are on the same scale; the pictures here are our Light Return tracer, and the Cut Performance Wheel sets it against any other cut and stone.
