Twenty-four crown mains and twelve stars ring the table. A single tier of twenty-four pavilion mains runs from the girdle to a pointed culet. There are no upper or lower halves, and the whole pavilion is cut at one angle. For a moissanite round on the classic eight-fold plan, see DG-Anteros. ## DG-M5 Cut specifications Measured from the delivered model, not quoted from a standard. **Category** House cuts **Facets** 85 planar facets (61 + 24 girdles = 85) **Outline** Length to width 1.000 **Total depth** 60.6% of width **Crown angle (main)** 32.0° **Pavilion angle (main)** 41.5° **Reference size** 8.15 x 8.15 x 4.94 mm at 1.94 ct in diamond **Volume** 110.09 mm³ **Cutting file accuracy** Every crown and pavilion facet within 0.004° of the 3D model (average 0.003°) **Index gear** 96 **Symmetry** 12-fold mirror-image symmetry **Tiers** 2 crown, 1 pavilion **Files** STEP, 3DM, STL, OBJ, FBX, GLB, GemCad .asc, tier table, diagram ## Face-up and profile *Face-up facet diagram of the DG-M5 Cut* Face-up: the crown facets, drawn from the model's own edges. *Side profile of the DG-M5 Cut* Profile: 60.6% total depth. ![Light Return map of the DG-M5 Cut in moissanite: a computed render showing direct, indirect and contrast light across the face-up stone.](https://digitalgemology.com/img/cuts/bl-m5-lightmap.webp?v=ad790401) Light Return map of the DG-M5 Cut in moissanite.

Its brilliance and fire together are highest there: 98 for brilliance and 100 for fire.** In diamond it scores 97 for brilliance and 67 for fire, against 93 and 78 for the T73 benchmark. Its scintillation, 85, comes from its pattern of facets, so it is the same in every stone. **Brilliance, fire and scintillation of the DG-M5 Cut in seven gemstones, out of 100, with the T73 Round Brilliant benchmark in each** | Gemstone | Brilliance | Fire | Scintillation | | --- | --- | --- | --- | | [Diamond](https://digitalgemology.com/gemstones/diamond) | 97 (T73 benchmark 93) | 67 (T73 benchmark 78) | 85 (T73 benchmark 80) | | [Moissanite](https://digitalgemology.com/gemstones/moissanite) *Best overall* *Highest fire* | 98 (T73 benchmark 86) | 100 (T73 benchmark 97) | 85 (T73 benchmark 80) | | [Cubic Zirconia](https://digitalgemology.com/gemstones/cubic-zirconia) | 91 (T73 benchmark 98) | 73 (T73 benchmark 87) | 85 (T73 benchmark 80) | | [Ruby](https://digitalgemology.com/gemstones/ruby) *Highest brilliance* | 100 (T73 benchmark 94) | 39 (T73 benchmark 37) | 85 (T73 benchmark 80) | | [Sapphire](https://digitalgemology.com/gemstones/sapphire) *Highest brilliance* | 100 (T73 benchmark 94) | 39 (T73 benchmark 37) | 85 (T73 benchmark 80) | | [Emerald](https://digitalgemology.com/gemstones/emerald) | 90 (T73 benchmark 78) | 46 (T73 benchmark 39) | 85 (T73 benchmark 80) | | [Amethyst](https://digitalgemology.com/gemstones/amethyst) | 85 (T73 benchmark 72) | 50 (T73 benchmark 36) | 85 (T73 benchmark 80) | Score out of 100 T73 Round Brilliant, our benchmark, in the same stone **Best overall:** the highest brilliance and fire together Brilliance is the share of face-up light that the stone returns. Fire is the share of that light that splits into color. Both come from our face-up light census. Scintillation is the sparkle that the facets give as the stone moves, and we read it from its facets.

Their head-on figures are in the table below. ### Head-on reflection, critical angle and weight in each stone The same geometry behaves differently in every material. Light that meets a pavilion facet at less than the critical angle of the stone does not reflect. It passes straight out of the back and shows face-up as a window. For each stone, we measured how much of the pavilion of this model, seen face-down, is steeper than that angle. We also measured what the model weighs at its reference size. Head-on light in amethyst: a steep facet reflects it, a shallow facet lets it out of the back. | Stone | Refractive index | Critical angle | Pavilion reflecting head-on light | Weight at this size | Verdict | | --- | --- | --- | --- | --- | --- | | [Diamond](https://digitalgemology.com/gemstones/diamond) | 2.417 | 24.4° | 100% | 1.94 ct | Holds head-on light | | [Moissanite](https://digitalgemology.com/gemstones/moissanite) | 2.648 to 2.691 | 22.2° | 100% | 1.77 ct | Holds head-on light | | [Cubic Zirconia](https://digitalgemology.com/gemstones/cubic-zirconia) | 2.15 to 2.18 | 27.7° | 100% | 3.19 ct | Holds head-on light | | [Ruby](https://digitalgemology.com/gemstones/ruby) | 1.762 to 1.770 | 34.6° | 100% | 2.20 ct | Holds head-on light | | [Sapphire](https://digitalgemology.com/gemstones/sapphire) | 1.762 to 1.770 | 34.6° | 100% | 2.20 ct | Holds head-on light | | [Emerald](https://digitalgemology.com/gemstones/emerald) | 1.577 to 1.583 | 39.4° | 100% | 1.50 ct | Holds head-on light | | [Amethyst](https://digitalgemology.com/gemstones/amethyst) | 1.544 to 1.553 | 40.4° | 100% | 1.46 ct | Holds head-on light | | [Topaz](https://digitalgemology.com/gemstones/topaz) | 1.606 to 1.644 | 38.5° | 100% | 1.95 ct | Holds head-on light | | [Spinel](https://digitalgemology.com/gemstones/spinel) | 1.712 to 1.747 | 35.7° | 100% | 1.99 ct | Holds head-on light | | [Demantoid](https://digitalgemology.com/gemstones/demantoid) | 1.881 to 1.888 | 32.1° | 100% | 2.12 ct | Holds head-on light | | [Zircon](https://digitalgemology.com/gemstones/zircon) | 1.925 to 1.984 | 31.3° | 100% | 2.57 ct | Holds head-on light | | [Tourmaline](https://digitalgemology.com/gemstones/tourmaline) | 1.603 to 1.655 | 38.6° | 100% | 1.72 ct | Holds head-on light | | [Peridot](https://digitalgemology.com/gemstones/peridot) | 1.650 to 1.690 | 37.3° | 100% | 1.84 ct | Holds head-on light | | [Tanzanite](https://digitalgemology.com/gemstones/tanzanite) | 1.685 to 1.707 | 36.4° | 100% | 1.84 ct | Holds head-on light | | [YAG](https://digitalgemology.com/gemstones/yag) | 1.833 | 33.1° | 100% | 2.50 ct | Holds head-on light | | [Pyrope](https://digitalgemology.com/gemstones/pyrope) | 1.730 to 1.766 | 35.3° | 100% | 2.07 ct | Holds head-on light | | [Almandine](https://digitalgemology.com/gemstones/almandine) | 1.750 to 1.830 | 34.8° | 100% | 2.27 ct | Holds head-on light | | [Spessartine](https://digitalgemology.com/gemstones/spessartine) | 1.790 to 1.830 | 34.0° | 100% | 2.29 ct | Holds head-on light | | [Grossular](https://digitalgemology.com/gemstones/grossular) | 1.730 to 1.760 | 35.3° | 100% | 2.00 ct | Holds head-on light | | [Chrysoberyl](https://digitalgemology.com/gemstones/chrysoberyl) | 1.746 to 1.755 | 34.9° | 100% | 2.05 ct | Holds head-on light | | [Kunzite](https://digitalgemology.com/gemstones/kunzite) | 1.660 to 1.676 | 37.0° | 100% | 1.75 ct | Holds head-on light | | [Iolite](https://digitalgemology.com/gemstones/iolite) | 1.542 to 1.551 | 40.4° | 100% | 1.44 ct | Holds head-on light | | [Morganite](https://digitalgemology.com/gemstones/morganite) | 1.572 to 1.600 | 39.5° | 100% | 1.57 ct | Holds head-on light | | [GGG](https://digitalgemology.com/gemstones/ggg) | 1.970 | 30.5° | 100% | 3.88 ct | Holds head-on light | | [Strontium titanate](https://digitalgemology.com/gemstones/strontium-titanate) | 2.409 | 24.5° | 100% | 2.82 ct | Holds head-on light | | [Synthetic rutile](https://digitalgemology.com/gemstones/synthetic-rutile) | 2.616 to 2.903 | 22.5° | 100% | 2.34 ct | Holds head-on light | Head-on light, first reflection.

STEP is the exact faceted solid for CAD, and 3DM is for Rhino. STL and OBJ are meshes. FBX is for Blender, 3ds Max, Maya, Cinema 4D, Unity and Unreal. GLB is for the web and AR. All are in millimeters at real-world scale, with 85 planar facets. ### Is there a faceting diagram for the DG-M5 Cut? Yes. The cutting files contain a GemCad .asc design (61 + 24 girdles = 85 facets, 96 index, 12-fold mirror-image symmetry) and a printable faceting diagram. They also contain a tier table in CSV, with the angles, indices and cutting order. ### Does the DG-M5 Cut work in sapphire, emerald or amethyst? We measured the pavilion of this model against the critical angle of each stone. In Diamond, Moissanite, Cubic Zirconia, Ruby, Sapphire, Emerald, Amethyst, the whole pavilion reflects head-on light. ### How accurate is the DG-M5 Cut cutting file? We check it facet by facet against the 3D model that it was written from. Every crown and pavilion facet within 0.004° of the 3D model (average 0.003°). The angles are the ones you set on the machine. The 3D model is the same stone that you render or set. ### How big is the DG-M5 Cut model, and what does it weigh? The model measures 8.15 x 8.15 x 4.94 mm, which is 1.94 ct in diamond. At the same size, it weighs 1.77 ct in moissanite, 3.19 ct in cubic zirconia, 2.20 ct in ruby, 2.20 ct in sapphire, 1.50 ct in emerald, 1.46 ct in amethyst. You can scale it uniformly to any size: the weight follows the cube of the size. Twice the size holds eight times the material, so it weighs eight times as much. ### Can I 3D print or cast the DG-M5 Cut model? Yes. The mesh is watertight and manifold, with outward normals and no duplicate vertices, so it prints and casts without repair. Use the STEP file when you need the exact faceted solid in CAD. ## Learn Free lessons that use this cut, with videos where they have one. - [Why moissanite shows more fire than diamond](https://digitalgemology.com/learn/diamond-vs-moissanite/why-moissanite-has-more-fire) [All lessons](https://digitalgemology.com/learn) ## More house cuts - [DG-Miliano Cut](https://digitalgemology.com/cuts/dg-miliano) - [DG-Rafaello Cut](https://digitalgemology.com/cuts/dg-rafaello) - [DG-Bowtie Cut](https://digitalgemology.com/cuts/dg-bowtie) - [DG-Elongated Hexagon Cut](https://digitalgemology.com/cuts/dg-elongated-hexagon) - [DG-Cabochon Cut](https://digitalgemology.com/cuts/dg-cabochon) - [DG-Octagonal Kite Cut](https://digitalgemology.com/cuts/dg-octagonal-kite) - [Elongated Hexagonal Bipyramid Cut](https://digitalgemology.com/cuts/elongated-hexagonal-bipyramid) ## Get the DG-M5 Cut files *6 formats* *Millimeters* *Watertight* ### DG-M5 Cut 3D files The DG-M5 Cut as exact geometry: 85 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/54385fa7-71f5-4b7f-8677-3e9a894ce65b) *GemCad* *96 index* ### DG-M5 Cut cutting files The DG-M5 Cut as a faceting design: 61 + 24 girdles = 85 facets, 96 index, 12-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/1cd9a8e2-be07-4ea8-9060-d31ac824756a) Not sure the files open in your software?
