Light Return map of the Mazarin Cut in almandine, face-up, from our own tracer at refractive index 1.75. Red, green and blue return light to the eye; gray leaks.

## Mazarin Cut Almandine

Almandine has a refractive index of 1.750 to 1.830 and a dispersion of 0.027. Its critical angle, from the low end of that range, is 34.8°, 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, 1.790, the midpoint of the published range, and a fire spread of 0.023, 0.86 of the published dispersion. Every picture here is our Light Return tracer at 1.750, and every figure is from the same light census that scores the other gemstones; the 3D Gemstone Simulator shows the Mazarin Cut in almandine live.

The Mazarin Cut has 42 facets, a table of 57.5% of its width and a total depth of 68.8% of its width; its pavilion mains sit at 44.3°. In almandine, the census returns 59 of 100 for brilliance and 58 for fire, against 95 and 54 for the T73, our benchmark, in the same stone; the same Mazarin Cut in diamond reads 65 and 63.

## Is almandine good in a Mazarin? Pros and cons, measured

### Pros

No figure ahead by our thresholds

### Cons

- [Returns less light than the T73 in almandine](https://digitalgemology.com/gemstones/almandine/mazarin#con-brilliance) 59 vs 95
- [Leaks more light than the T73 in almandine](https://digitalgemology.com/gemstones/almandine/mazarin#con-leak) 36 vs 5
- [Fewer facets, less sparkle](https://digitalgemology.com/gemstones/almandine/mazarin#con-scint) 61 vs 80

Compared with the T73 Round Brilliant in almandine and with the Mazarin 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).

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=mazarin&stone=almandine); these are the same census figures as our [Cut Performance Index](https://digitalgemology.com/learn/cut-performance-index).

## What the Mazarin Cut gains in almandine

Against the T73 in almandine and the same cut in diamond, no figure of the Mazarin Cut is ahead by the thresholds above. Its figures are in the wheel and the FAQ; [Almandine](https://digitalgemology.com/gemstones/almandine) ranks every cut we score in almandine.

## What the Mazarin Cut gives up in almandine

### Returns less light than the T73 in almandine

**Brilliance 59** against 95 for the T73 Round Brilliant in almandine: 36 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 almandine, whose critical angle is 34.8°, the Mazarin Cut returns 59 of 100 and the T73 95. The Mazarin Cut's pavilion mains sit at 44.3°, the T73's at 40.8°. The maps below show where each stone's light returns from and where it leaks.

Mazarin Cut in almandine · Brilliance 59

T73 Round Brilliant in almandine · Brilliance 95

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/almandine/dg-m5) reads 99 for brilliance in almandine, the best of the cuts we score there.

### Leaks more light than the T73 in almandine

**Leakage 36** against 5 for the T73 Round Brilliant in almandine: 31 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 Mazarin Cut leaks 36% in almandine against 5% for the T73 in almandine. Grey in the maps below is leaking light; the share under each picture is that picture's own.

Mazarin Cut in almandine · Leakage 36

0° · 42% leak

10° · 39% leak

20° · 29% leak

30° · 41% leak

T73 Round Brilliant in almandine · Leakage 5

0° · 1% leak

10° · 10% leak

20° · 28% leak

30° · 30% leak

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-M5](https://digitalgemology.com/gemstones/almandine/dg-m5) reads 1% for leakage in almandine, the best of the cuts we score there.

[Try it yourself: Tilt it yourself in the simulator's light map](https://digitalgemology.com/tools/3d_gemstone_simulator?cut=mazarin&stone=almandine&ct=1.00&view=up&map=1&turn=0)

### Fewer facets, less sparkle

**Scintillation 61** against 80 for the T73 Round Brilliant in almandine: 19 points lower

Scintillation follows the number of facets the stone shows: 100 × (1 − e^(−facets / 45)). The Mazarin Cut has 42 facets and the T73 73, so 61 against 80. It depends on the geometry alone, so it is the same in every stone.

*Facet diagram of the Mazarin Cut: its crown, seen face-up, 42 facets in all*

Mazarin Cut · 42 facets · Scintillation 61

*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 helps:** [the DG-Miliano](https://digitalgemology.com/gemstones/almandine/dg-miliano) reads 98 for scintillation in almandine, the best of the cuts we score there.

[Try it yourself: Compare the Scintillation spoke in the Cut Performance Wheel](https://digitalgemology.com/tools/cut-performance-wheel?cut=mazarin&stone=almandine)

### Heavier than the same cut in diamond

**1.55 ct** at 6.5 mm, against 1.32 ct for the same cut in diamond (+17%)

Weight follows specific gravity: 4.125 for almandine against 3.52 for diamond, so the same model at the same size weighs 1.55 ct here and 1.32 ct in diamond, 6.5 mm across. Nothing about the light changes with it.

*Weight of a 6.5 mm Mazarin Cut: 1.55 ct in almandine, 1.32 ct in diamond*

A Mazarin Cut 6.5 mm across, weighed from the model's measured volume and each stone's specific gravity.

## Our verdict on the Mazarin Cut in almandine

Against the T73 in almandine and the same cut in diamond, no figure of the Mazarin Cut is ahead by our thresholds. The catch: it returns less light than the T73, leaks more light than the T73, has fewer facets to sparkle with and weighs more than in diamond.

If that catch matters more to you, [the DG-M5](https://digitalgemology.com/gemstones/almandine/dg-m5) reads 99 for brilliance in almandine, 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 Mazarin Cut model we traced.

## Mazarin Cut Almandine: questions

### Is the Mazarin a good cut for almandine?

In our census the Mazarin Cut returns 59 of 100 for brilliance and 58 for fire in almandine, against 95 and 54 for the T73 in the same stone. Against that round and against the same cut in diamond it has 0 pros and 4 cons by our thresholds; the summary above names them.

### What pavilion angle does almandine need?

At least 36.3° for a round design: almandine's critical angle is 34.8°, 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 Mazarin Cut's pavilion mains sit at 44.3°.

### How much does a Mazarin weigh in almandine?

At 6.5 mm across, 1.55 ct in almandine, against 1.32 ct for the same cut in diamond (+17%): almandine's specific gravity is 4.125, diamond's 3.52.

### Can I see the Mazarin in almandine in 3D?

Yes: the 3D Gemstone Simulator renders it live, with almandine's own refractive index and dispersion. Almandine 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.
