DG-Anteros Diamond: a moissanite round that stays level with the T73 on light
Brilliance 95 · Fire 74 · Scintillation 80 · in our census, where the T73 scores 93 · 78 · 80 in diamond
DG-Anteros is our round re-solved for moissanite. In diamond it keeps level with the T73 on light, and loses on fire and on how it holds light when tipped.
Rendered in our 3D Gemstone Simulator from the DG-Anteros model, 1.00 ct, studio light.
DG-Anteros Diamond
Start from the T73, keep its 73 facets and its table, ease the crown and move the pavilion cone to suit moissanite's stronger bending of light: that is DG-Anteros. The model has a 53.5% table, a 33.0° crown and a 40.1° pavilion, and it is 59.4% deep.
This page puts it back in diamond and measures it against the T73 Round Brilliant. It is matched to its material rather than better in general, and the census shows that: no pros by our margins, two cons. We publish it so anyone weighing the two rounds in diamond can see the numbers.
Is DG-Anteros a good choice for diamond? Pros and cons
Pros
None by our margins: brilliance and leakage are level with the T73.
Compared with the T73 Round Brilliant in diamond.
A difference counts from 3 points (Brilliance, Fire, Tilt, Leakage), 5 (Scintillation,
Symmetry), 2 (Spread) 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.

No score beats the T73 in diamond by our thresholds. Brilliance is 95 against 93, scintillation 80 against 80, and both leak 2% of the light. Head-on, its Light Return map even shows a little less grey than the T73's. What it offers in diamond is the T73's facet plan with angles tuned for another stone: of interest to a cutter comparing the two, not a reason to choose it.
Where DG-Anteros falls short in diamond
Keeps less light when tipped
Tilt 85 against 92 for the T73 Round Brilliant in diamond: 7 points lower
At 20° it holds 85 of its face-up light, against 92 for the T73. The strip shows the pattern: face-up it has less grey than the T73, from 10° on it has more, and by 30° nearly twice as much. Angles chosen for moissanite let tilted light out of a diamond sooner.

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; grey is light leaving through the pavilion. The share under each frame is that picture's own.
What helps: The pavilion, at 40.1°, is already above diamond's 38.9° guide minimum, so steepening is not the fix. For a diamond round that holds its light when tipped, the T73 Round Brilliant Diamond keeps 92 and DG-Rafaello Diamond 97.
Fire 74 against 78 for the T73 Round Brilliant in diamond: 4 points lower
The eased crown changes how light is split into colour on its way out, and in diamond the result is fire below the benchmark's. The gap is small but clears our threshold.
DG-Anteros in diamond · Fire 74
T73 Round Brilliant in diamond · Fire 78
Look at the coloured flashes: those are fire. Same light, same size, same face-up angle; rendered by our 3D Gemstone Simulator from each cut's own model.
What helps: For more fire with the same light, DG-Miliano Diamond reaches 82; the T73 itself gives 78.
In diamond, we would choose the T73 over DG-Anteros: the same facet plan, the same light, more fire and a steadier hold when tipped. DG-Anteros earns its place in moissanite, where it returns more light than the T73; see DG-Anteros Moissanite.
If you cut both stones and want one design for each, pair DG-Anteros for moissanite with the T73 Round Brilliant Diamond for diamond. For the most light of any round in diamond, DG-M5 Diamond at 97.
DG-Anteros Diamond: questions
Is DG-Anteros good in diamond?
It is level with the T73 on light, 95 against 93, but behind on fire (74 against 78) and on Tilt (85 against 92). In diamond the T73 is the better choice.
Why does DG-Anteros look different in diamond?
Its angles were solved for moissanite. In diamond, the site's own comparison shows its arrows turning dark and its hearts flooding.
DG-Anteros or T73 for a diamond?
The T73. Both leak 2% and return nearly the same light, but the T73 has more fire and keeps more light at an angle.
What does a 6.5 mm DG-Anteros diamond weigh?
0.97 ct, a little lighter than a T73 of that width: the model is 59.4% deep against 61.7%.
