Light Return map of the Teardrop Cut in topaz, face-up, from our own tracer at refractive index 1.606. Red, green and blue return light to the eye; gray leaks.

## Teardrop Cut Topaz

Topaz has a refractive index of 1.606 to 1.644 and a dispersion of 0.014. Its critical angle, from the low end of that range, is 38.5°, so a round design needs a pavilion of at least 38.5° for head-on light to reflect off both sides of the pavilion and leave through the table. We trace it with one index, 1.625, the midpoint of the published range, and a fire spread of 0.012, 0.86 of the published dispersion. Every picture here is our Light Return tracer at 1.606, and every figure is from the same light census that scores the other gemstones; the 3D Gemstone Simulator shows the Teardrop Cut in topaz live.

The Teardrop Cut has 74 facets and a total depth of 60.0% of its width; its pavilion mains sit at 38.5°. In topaz, the census returns 57 of 100 for brilliance and 61 for fire, against 86 and 35 for the T73, our benchmark, in the same stone; the same Teardrop Cut in diamond reads 46 and 89.

Compared with the T73 Round Brilliant in topaz and with the Teardrop 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 Teardrop Cut in topaz (white) against the T73 Round Brilliant in topaz (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 topaz: ahead on 3, behind on 5.

- Global 64, the comparison 75, difference −11
- Brilliance 57, the comparison 86, difference −29
- Fire 61, the comparison 35, difference +26
- Scintillation 81, the comparison 80, difference +1
- Spread 101, the comparison 100, difference +1
- Symmetry 98, the comparison 100, difference −2
- Shape-norm 66, the comparison 92, difference −26
- Tilt 50, the comparison 74, difference −24

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

## What the Teardrop Cut gains in topaz

### Faces up larger for its weight

**Face-up size 116** against 100 for the T73 Round Brilliant in topaz (T73 = 100): 16% more face-up area for the same weight

Face-up size is the outline's area per carat, measured from each model (T73 = 100): 116 for the Teardrop 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 Teardrop Cut at 1.00 ct in topaz: 8.63 x 5.97 mm, drawn to scale*

Teardrop Cut · 8.63 x 5.97 mm at 1.00 ct · Face-up size 116

*Face-up outline of the T73 Round Brilliant at 1.00 ct in topaz: 6.47 mm, drawn to scale*

T73 Round Brilliant · 6.47 mm at 1.00 ct · Face-up size 100

Both stones weigh 1.00 ct in topaz 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.

## What the Teardrop Cut gives up in topaz

### Loses more light when tilted than in diamond

**Tilt 50** against 80 for the Teardrop Cut in diamond: 30 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 Teardrop Cut keeps 50 against 80 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.

Teardrop Cut in topaz · Tilt 50

0° · 32% leak

10° · 35% leak

20° · 44% leak

30° · 51% leak

Teardrop Cut in diamond · Tilt 80

0° · 34% leak

10° · 35% leak

20° · 37% leak

30° · 44% 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 T105 Round Brilliant](https://digitalgemology.com/gemstones/topaz/t105-round-brilliant) reads 78 for tilt in topaz, the best of the cuts we score there.

[Try it yourself: Compare the Tilt spoke in the Cut Performance Wheel](https://digitalgemology.com/tools/cut-performance-wheel?cut=teardrop&stone=topaz&vs=teardrop&vsstone=diamond)

### Returns less light than the T73 in topaz

**Brilliance 57** against 86 for the T73 Round Brilliant in topaz: 29 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 topaz, whose critical angle is 38.5°, the Teardrop Cut returns 57 of 100 and the T73 86. The Teardrop Cut's pavilion mains sit at 38.5°, the T73's at 40.8°. The maps below show where each stone's light returns from and where it leaks.

Teardrop Cut in topaz · Brilliance 57

T73 Round Brilliant in topaz · Brilliance 86

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/topaz/dg-m5) reads 96 for brilliance in topaz, 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=teardrop&stone=topaz&ct=1.00&view=up&map=1&turn=0)

### Less fire in topaz than in diamond

**Fire 61** against 89 for the Teardrop Cut in diamond: 28 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 (0.012 in topaz) and counts a ray as fire when the two directions differ by more than 0.6°. The Teardrop Cut reads 61 against 89 for the same cut in diamond. The figure is the census's; the 3D Gemstone Simulator renders topaz'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=teardrop&stone=topaz&ct=1.00&view=up&lighting=sun&turn=0): the Teardrop Cut in topaz under the sunny-day lighting.

**What helps:** [the Oval Cut](https://digitalgemology.com/gemstones/topaz/oval) reads 68 for fire in topaz, 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=teardrop&stone=topaz&ct=1.00&view=up&lighting=sun&turn=0)

### Leaks more light than the T73 in topaz

**Leakage 32** against 14 for the T73 Round Brilliant in topaz: 18 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 Teardrop Cut leaks 32% in topaz against 14% for the T73 in topaz. Grey in the maps below is leaking light; the share under each picture is that picture's own.

Teardrop Cut in topaz · Leakage 32

0° · 32% leak

10° · 35% leak

20° · 44% leak

30° · 51% leak

T73 Round Brilliant in topaz · Leakage 14

0° · 10% leak

10° · 28% leak

20° · 32% leak

30° · 37% 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/topaz/dg-m5) reads 4% for leakage in topaz, 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=teardrop&stone=topaz&ct=1.00&view=up&map=1&turn=0)

## Our verdict on the Teardrop Cut in topaz

Pick the Teardrop Cut in topaz for this: it faces up larger for its weight. The catch: it loses more light when tilted than in diamond, returns less light than the T73, shows less fire than in diamond and leaks more light than the T73.

If that catch matters more to you, [the T105 Round Brilliant](https://digitalgemology.com/gemstones/topaz/t105-round-brilliant) reads 78 for tilt in topaz, 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 Teardrop Cut model we traced.

## Teardrop Cut Topaz: questions

### Is the Teardrop a good cut for topaz?

In our census the Teardrop Cut returns 57 of 100 for brilliance and 61 for fire in topaz, against 86 and 35 for the T73 in the same stone. Against that round and against the same cut in diamond it has 1 pro and 4 cons by our thresholds; the summary above names them.

### What pavilion angle does topaz need?

At least 38.5° for a round design: topaz's critical angle is 38.5°, 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 Teardrop Cut's pavilion mains sit at 38.5°.

### How much does a Teardrop weigh in topaz?

At 6.5 mm across, 1.29 ct in topaz, against 1.28 ct for the same cut in diamond, the same weight to the per cent: topaz's specific gravity is 3.535, diamond's 3.52.

### Can I see the Teardrop in topaz in 3D?

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