Red, green and blue return light to the eye; gray leaks. ## DG-Anteros Pyrope Pyrope has a refractive index of 1.730 to 1.766 and a dispersion of 0.022. Its critical angle, from the low end of that range, is 35.3°, so a round design needs a pavilion of at least 36.2° for head-on light to reflect off both sides of the pavilion and leave through the table. We trace it with one index, 1.748, the midpoint of the published range, and a fire spread of 0.019, 0.86 of the published dispersion. Every picture here is our Light Return tracer at 1.730, and every figure is from the same light census that scores the other gemstones; the 3D Gemstone Simulator shows the DG-Anteros in pyrope 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 pyrope, the census returns 97 of 100 for brilliance and 57 for fire, against 94 and 50 for the T73, our benchmark, in the same stone; the same DG-Anteros in diamond reads 95 and 74. ## Is pyrope good in a DG-Anteros? Pros and cons, measured ### Pros - [Returns more light than the T73 in pyrope](https://digitalgemology.com/gemstones/pyrope/dg-anteros#pro-brilliance) 97 vs 94 - [Leaks less light than the T73 in pyrope](https://digitalgemology.com/gemstones/pyrope/dg-anteros#pro-leak) 2 vs 5 ### Cons - [Less fire in pyrope than in diamond](https://digitalgemology.com/gemstones/pyrope/dg-anteros#con-fire) 57 vs 74 - [Loses more light when tilted than in diamond](https://digitalgemology.com/gemstones/pyrope/dg-anteros#con-tiltStab) 76 vs 85 - [Heavier than the same cut in diamond](https://digitalgemology.com/gemstones/pyrope/dg-anteros#con-weight) 1.04 vs 0.97 ct Compared with the T73 Round Brilliant in pyrope 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 pyrope (white) against the T73 Round Brilliant in pyrope (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 pyrope: ahead on 6, level on 2. - Global 84, the comparison 81, difference +3 - Brilliance 97, the comparison 94, difference +3 - Fire 57, the comparison 50, difference +7 - Scintillation 80, the comparison 80, difference 0 - Spread 101, the comparison 100, difference +1 - Symmetry 100, the comparison 100, difference 0 - Shape-norm 105, the comparison 102, difference +3 - Tilt 76, the comparison 75, difference +1 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=pyrope); these are the same census figures as our [Cut Performance Index](https://digitalgemology.com/learn/cut-performance-index). ## What the DG-Anteros gains in pyrope ### Returns more light than the T73 in pyrope **Brilliance 97** against 94 for the T73 Round Brilliant in pyrope: 3 points higher 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 pyrope, whose critical angle is 35.3°, the DG-Anteros returns 97 of 100 and the T73 94. 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 pyrope · Brilliance 97 T73 Round Brilliant in pyrope · 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. [Try it yourself: Open this Light Return map in the simulator](https://digitalgemology.com/tools/3d_gemstone_simulator?cut=dg-anteros&stone=pyrope&ct=1.00&view=up&map=1&turn=0) ### Leaks less light than the T73 in pyrope **Leakage 2** against 5 for the T73 Round Brilliant in pyrope: 3 points lower 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 2% in pyrope against 5% for the T73 in pyrope. Grey in the maps below is leaking light; the share under each picture is that picture's own. DG-Anteros in pyrope · Leakage 2 0° · 0% leak 10° · 5% leak 20° · 23% leak 30° · 32% leak T73 Round Brilliant in pyrope · Leakage 5 0° · 0% leak 10° · 14% leak 20° · 28% leak 30° · 31% leak Each frame is the Light Return map with the stone tilted away from you by the angle shown; gray is leakage.

The DG-Anteros reads 57 against 74 for the same cut in diamond. The figure is the census's; the 3D Gemstone Simulator renders pyrope's fire live. The fire figure is the census's, traced at the refractive index minus and plus the fire spread.

The DG-Anteros keeps 76 against 85 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. DG-Anteros in pyrope · Tilt 76 0° · 0% leak 10° · 5% leak 20° · 23% leak 30° · 32% leak DG-Anteros in diamond · Tilt 85 0° · 2% leak 10° · 4% leak 20° · 12% leak 30° · 26% 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/pyrope/dg-miliano) reads 83 for tilt in pyrope, 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=dg-anteros&stone=pyrope&vs=dg-anteros&vsstone=diamond) ### Heavier than the same cut in diamond **1.04 ct** at 6.5 mm, against 0.97 ct for the same cut in diamond (+7%) Weight follows specific gravity: 3.76 for pyrope against 3.52 for diamond, so the same model at the same size weighs 1.04 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: 1.04 ct in pyrope, 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. [Try it yourself: Weights in every gemstone on the DG-Anteros page](https://digitalgemology.com/cuts/dg-anteros#stones) ## Our verdict on the DG-Anteros in pyrope Pick the DG-Anteros in pyrope for this: it returns more light than the T73 and leaks less light than the T73. The catch: it shows less fire than in diamond, loses more light when tilted than in diamond and weighs more than in diamond. If that catch matters more to you, [the DG-Elongated Hexagon](https://digitalgemology.com/gemstones/pyrope/dg-elongated-hexagon) reads 85 for fire in pyrope, 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 Pyrope: questions ### Is the DG-Anteros a good cut for pyrope? In our census the DG-Anteros returns 97 of 100 for brilliance and 57 for fire in pyrope, against 94 and 50 for the T73 in the same stone. Against that round and against the same cut in diamond it has 2 pros and 3 cons by our thresholds; the summary above names them. ### What pavilion angle does pyrope need? At least 36.2° for a round design: pyrope's critical angle is 35.3°, 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 pyrope? At 6.5 mm across, 1.04 ct in pyrope, against 0.97 ct for the same cut in diamond (+7%): pyrope's specific gravity is 3.76, diamond's 3.52. ### Can I see the DG-Anteros in pyrope in 3D? Yes: the 3D Gemstone Simulator renders it live, with pyrope's own refractive index and dispersion. Pyrope 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. ## Get the DG-Anteros Cut files *6 formats* *Millimeters* *Watertight* ### DG-Anteros Cut 3D files The DG-Anteros Cut as exact geometry: 73 planar facets, real-world scale, ready for CAD, rendering, printing and casting. - **STEP** Exact faceted solid for CAD - **3DM** Rhino, closed mesh on its own layer - **STL** Watertight mesh for printing and casting - **OBJ** Mesh for modeling and rendering - **FBX** Blender, 3ds Max, Maya, Cinema 4D, Unity, Unreal - **GLB** Web, AR and quick previews €14.99 · [Personal use](https://digitalgemology.com/licence) [Buy the 3D files](https://digitalgemology.lemonsqueezy.com/checkout/buy/2e4ad6fb-622c-4a41-b045-eab18e4b961d) *GemCad* *96 index* ### DG-Anteros Cut cutting files The DG-Anteros Cut as a faceting design: 57 + 16 girdles = 73 facets, 96 index, 8-fold mirror-image symmetry, ready for the machine. - **.asc** GemCad design file, 96 index gear - **.csv** Tier table: angles, indices and cutting order - **Diagram** Printable faceting diagram €12.99 · [Personal use](https://digitalgemology.com/licence) [Buy the cutting files](https://digitalgemology.lemonsqueezy.com/checkout/buy/54188a37-b56f-4120-a93c-c783b2e18a49) Not sure the files open in your software?
