DG-Elongated Hexagon Cubic Zirconia: the most fire we measure here, from very little light

Brilliance 16 · Fire 97 · Scintillation 51 · in our census, where the T73 scores 98 · 87 · 80 in cubic zirconia

Finished alike front and back, with a back flat that is a window by design. In CZ it scores the highest fire and the lowest brilliance we measure, and the census counts the light through that window as lost.

DG-Elongated Hexagon Cubic Zirconia

DG-Elongated Hexagon is an elongated hexagon with square points, 1.7 to 1, step cut alike on both faces: two steps either side of a six-facet girdle, a 50.0% table in front and a flat of the same size behind. It has 32 facets and is 45.3% deep, the shallowest cut in our CZ census.

Census note: its back flat is a window by design. The cut page leaves it out of the head-on figures, and the census counts the light through it as lost. Read its brilliance and leakage with that in mind.

It was drawn for emerald, and its two finished faces suit pendants and open settings where the back is on show.

Is DG-Elongated Hexagon a good cut for cubic zirconia? Pros and cons

Compared with the T73 Round Brilliant in cubic zirconia and with the DG-Elongated Hexagon 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.

What DG-Elongated Hexagon gives cubic zirconia

The most fire we measure in CZ

Fire 97 against 87 for the T73 Round Brilliant in cubic zirconia: 10 points higher

Fire 97 tops every cut in our CZ census and matches the same design in diamond, 97. It is colour from a small amount of light: with Brilliance at 16, little of what enters comes back to the eye at all.

A little more face for its weight

Face-up size 107 against 100 for the T73 Round Brilliant in cubic zirconia (T73 = 100): 7% more face-up area for the same weight

Measured from its outline, it covers 107 per carat against the T73's 100. At 45.3% deep it carries less weight under its face than the round, at 61.7%.

T73 Round Brilliant · 5.49 mm at 1.00 ct · Face-up size 100

Both stones weigh 1.00 ct in cubic zirconia and are drawn to the same scale in millimetres, from each cut's own model. Face-up size is the outline's area per carat, with the T73 at 100: a deeper stone, or a rounder outline, spreads less area for its weight.

The catch with DG-Elongated Hexagon in CZ

The least light of any cut we measure in CZ

Brilliance 16 against 98 for the T73 Round Brilliant in cubic zirconia: 82 points lower

Brilliance 16 against 98 for the T73. The census counts the light through the back window as lost, and that flat is as large as the table.

T73 round brilliant in cubic zirconia face-up Light Return map: red, green and blue show where the light returns from, grey shows where it leaks (Brilliance 98)

T73 Round Brilliant in cubic zirconia · Brilliance 98

Red, green and blue = light returning to the eye; grey = light leaving through the pavilion. 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 window is the design; closing it would make a different cut. Among long step outlines in CZ, the Emerald Cut Cubic Zirconia keeps far more light: 59.

Over two-thirds of the light leaks

Leakage 69 against 1 for the T73 Round Brilliant in cubic zirconia: 68 points higher

69% in our census, the highest share of any cut we measure in CZ; the diamond version loses 73%. Rays that meet the back flat square on pass straight through it.

What helps: Size changes nothing, and the window stays a window. The Emerald Cut Cubic Zirconia leaks 25%.

Heavier than diamond

2.97 ct at 6.5 mm, against 1.80 ct for the same cut in diamond (+65%)

Shallow as it is, CZ's density still tells: 6.5 mm wide, it weighs 2.97 ct here and 1.80 ct in diamond.

Fewer flashes than a round

Scintillation 51 against 80 for the T73 Round Brilliant in cubic zirconia: 29 points lower

32 facets, mostly steps, against the T73's 73: Scintillation 51 against 80, and the diamond version scores the same.

DG-Elongated Hexagon · 32 facets · Scintillation 51

T73 Round Brilliant · 73 facets · Scintillation 80

Scintillation follows the number of facets: more facets, more and smaller flashes as the stone moves. Count the facets in each crown. Drawn from each cut's own model.

What helps: This is the step plan. For more sparkle in a long outline, the Marquise Cut Cubic Zirconia scores 86.

Who DG-Elongated Hexagon in CZ suits

Choose DG-Elongated Hexagon for a pendant or an open setting where both faces show, and for colour rather than light. By our measure it is a weak stone for light in CZ, partly by design.

If light matters, the Emerald Cut Cubic Zirconia gives a long step outline with far more of it; for the most light in CZ, DG-Rafaello Cubic Zirconia.

DG-Elongated Hexagon Cubic Zirconia: questions

Why does DG-Elongated Hexagon score so low for brilliance?

Its back flat is a window by design, and our census counts the light through it as lost: Brilliance 16, with 69% leaking.

Does DG-Elongated Hexagon have the most fire in CZ?

Yes, 97, the highest of the cuts we measure in CZ. It comes with very little returned light.

Can DG-Elongated Hexagon be seen from both sides?

Yes: both faces are finished, so it reads the same from either side.

What does a 6.5 mm wide DG-Elongated Hexagon CZ weigh?

2.97 ct, against 1.80 ct in diamond.
