## About the DG-Elongated Hexagon Cut

An elongated hexagon with square points, step cut the same on both faces. It has two steps on each side of a six-facet girdle, a table in front and a flat of the same size behind. It is drawn for emerald.

Both faces are finished, so it looks the same from either side. This suits pendants and open settings where the back is visible. The back flat is a window by design, so the head-on figures on this page leave it out. In emerald and amethyst, the steps beside the table also sit below the critical angle and let some light through.

## How the DG-Elongated Hexagon Cut performs in seven gemstones

**The DG-Elongated Hexagon Cut was drawn for emerald, where it scores 25 for brilliance and 69 for fire. It performs best in moissanite (20 for brilliance, 93 for fire) and cubic zirconia (16 for brilliance, 97 for fire), which tie on brilliance and fire together.** Its brilliance peaks in ruby and sapphire, at 27. In diamond it scores 12 for brilliance and 97 for fire, against 93 and 78 for the T73 benchmark. Its scintillation, 51, comes from its pattern of facets, so it is the same in every stone. Its back flat is a window by design, and these scores count the light through it as lost.

**Brilliance, fire and scintillation of the DG-Elongated Hexagon Cut in seven gemstones, out of 100, with the T73 Round Brilliant benchmark in each**

| Gemstone | Brilliance | Fire | Scintillation |

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. They are the same figures as the [Cut Performance Wheel](https://digitalgemology.com/tools/cut-performance-wheel?cut=dg-elongated-hexagon&stone=moissanite), where you can compare the DG-Elongated Hexagon Cut with any other cut.

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. The back flat of this two-sided stone is a window by design, so the figure leaves it out.

Head-on light in amethyst: a steep facet reflects it, a shallow facet lets it out of the back.

## DG-Elongated Hexagon Cut: questions

### What files come with the DG-Elongated Hexagon Cut 3D model?

Six formats. 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 32 planar facets.

### Is there a faceting diagram for the DG-Elongated Hexagon Cut?

Yes. The cutting files contain a GemCad .asc design (26 + 6 girdles = 32 facets, 96 index, 2-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-Elongated Hexagon 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, the whole pavilion reflects head-on light. In Emerald, Amethyst, part of the pavilion lets light out of the back, so we advise a steeper pavilion.

### How accurate is the DG-Elongated Hexagon Cut cutting file?

We check it facet by facet against the 3D model that it was written from. Every crown and pavilion facet within under 0.001° of the 3D model (average under 0.001°). 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-Elongated Hexagon Cut model, and what does it weigh?

The model measures 11.44 x 6.73 x 3.05 mm, which is 2.00 ct in diamond. At the same size, it weighs 1.83 ct in moissanite, 3.30 ct in cubic zirconia, 2.27 ct in ruby, 2.27 ct in sapphire, 1.55 ct in emerald, 1.51 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-Elongated Hexagon 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.
