Brilliance 89 · Fire 74 · Scintillation 80 · in our census, where the T73 scores 98 · 76 · 80 in GGG

How the DG-Anteros handles light in GGG, measured: brilliance 89, fire 74 and 10% leakage, set against the T73 in the same stone and against the same cut in diamond.

Light Return map of the DG-Anteros in GGG, face-up, from our own tracer at refractive index 1.97. Red, green and blue return light to the eye; gray leaks.

## DG-Anteros GGG

GGG has a refractive index of 1.970 and a dispersion of 0.045. Its critical angle, from the low end of that range, is 30.5°, so a round design needs a pavilion of at least 37.4° for head-on light to reflect off both sides of the pavilion and leave through the table. We trace it with one index, 1.970, the midpoint of the published range, and a fire spread of 0.039, 0.86 of the published dispersion. Every picture here is our Light Return tracer at 1.970, and every figure is from the same light census that scores the other gemstones; the 3D Gemstone Simulator shows the DG-Anteros in GGG live.

The DG-Anteros has 73 facets, a table of 53.5% of its width and a total depth of 59.4% of its width; its pavilion mains sit at 40.1°. In GGG, the census returns 89 of 100 for brilliance and 74 for fire, against 98 and 76 for the T73, our benchmark, in the same stone; the same DG-Anteros in diamond reads 95 and 74.

## Is GGG good in a DG-Anteros? Pros and cons, measured

### Pros

No figure ahead by our thresholds

### Cons

- [Heavier than the same cut in diamond](https://digitalgemology.com/gemstones/ggg/dg-anteros#con-weight) 1.94 vs 0.97 ct
- [Returns less light than the T73 in GGG](https://digitalgemology.com/gemstones/ggg/dg-anteros#con-brilliance) 89 vs 98
- [Leaks more light than the T73 in GGG](https://digitalgemology.com/gemstones/ggg/dg-anteros#con-leak) 10 vs 2

Compared with the T73 Round Brilliant in GGG and with the DG-Anteros 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 DG-Anteros in GGG (white) against the T73 Round Brilliant in GGG (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 ggg: ahead on 2, level on 2, behind on 4.

- Global 87, the comparison 90, difference −3
- Brilliance 89, the comparison 98, difference −9
- Fire 74, the comparison 76, difference −2
- Scintillation 80, the comparison 80, difference 0
- Spread 101, the comparison 100, difference +1
- Symmetry 100, the comparison 100, difference 0
- Shape-norm 96, the comparison 105, difference −9
- Tilt 94, the comparison 82, difference +12

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

## What the DG-Anteros gains in GGG

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

## What the DG-Anteros gives up in GGG

### Heavier than the same cut in diamond

**1.94 ct** at 6.5 mm, against 0.97 ct for the same cut in diamond (+100%)

Weight follows specific gravity: 7.05 for GGG against 3.52 for diamond, so the same model at the same size weighs 1.94 ct here and 0.97 ct in diamond, 6.5 mm across. Nothing about the light changes with it.

*Weight of a 6.5 mm DG-Anteros: 1.94 ct in GGG, 0.97 ct in diamond*

A DG-Anteros 6.5 mm across, weighed from the model's measured volume and each stone's specific gravity.

### Returns less light than the T73 in GGG

**Brilliance 89** against 98 for the T73 Round Brilliant in GGG: 9 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 GGG, whose critical angle is 30.5°, the DG-Anteros returns 89 of 100 and the T73 98. The DG-Anteros's pavilion mains sit at 40.1°, the T73's at 40.8°. The maps below show where each stone's light returns from and where it leaks.

DG-Anteros in GGG · Brilliance 89

T73 Round Brilliant in GGG · Brilliance 98

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-Broken Hearts and Arrows](https://digitalgemology.com/gemstones/ggg/dg-broken-hearts-and-arrows) reads 98 for brilliance in GGG, the best of the cuts we score there.

### Leaks more light than the T73 in GGG

**Leakage 10** against 2 for the T73 Round Brilliant in GGG: 8 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 DG-Anteros leaks 10% in GGG against 2% for the T73 in GGG. Grey in the maps below is leaking light; the share under each picture is that picture's own.

DG-Anteros in GGG · Leakage 10

0° · 10% leak

10° · 8% leak

20° · 13% leak

30° · 21% leak

T73 Round Brilliant in GGG · Leakage 2

0° · 0% leak

10° · 4% leak

20° · 14% leak

30° · 23% 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-Broken Hearts and Arrows](https://digitalgemology.com/gemstones/ggg/dg-broken-hearts-and-arrows) reads 2% for leakage in GGG, the best of the cuts we score there.

## Our verdict on the DG-Anteros in GGG

Against the T73 in GGG and the same cut in diamond, no figure of the DG-Anteros is ahead by our thresholds. The catch: it weighs more than in diamond, returns less light than the T73 and leaks more light than the T73.

If that catch matters more to you, [the DG-Broken Hearts and Arrows](https://digitalgemology.com/gemstones/ggg/dg-broken-hearts-and-arrows) reads 98 for brilliance in GGG, 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 DG-Anteros model we traced.

## DG-Anteros GGG: questions

### Is the DG-Anteros a good cut for GGG?

In our census the DG-Anteros returns 89 of 100 for brilliance and 74 for fire in GGG, against 98 and 76 for the T73 in the same stone. Against that round and against the same cut in diamond it has 0 pros and 3 cons by our thresholds; the summary above names them.

### What pavilion angle does GGG need?

At least 37.4° for a round design: GGG's critical angle is 30.5°, 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 DG-Anteros's pavilion mains sit at 40.1°.

### How much does a DG-Anteros weigh in GGG?

At 6.5 mm across, 1.94 ct in GGG, against 0.97 ct for the same cut in diamond (+100%): GGG's specific gravity is 7.05, diamond's 3.52.

### Can I see the DG-Anteros in GGG in 3D?

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