Hexagon Diamond Guide

Harsh Shah, Director at PASAVAJA Gems LLP and Graduate Diamonds (GIA), sources hexagons from cutters who work them deliberately rather than as a way to save a flawed rough. That distinction decides everything: a hexagon cut with intent holds even, geometric flashes across all six sides, while a salvaged one goes flat in the corners.

This guide covers everything you need to know about hexagon diamonds: what they are, how they are cut, how they compare to similar geometric shapes, what settings work best, and how to source one.

What Is a Hexagon Diamond?

A hexagon diamond is a six-sided diamond with equal-length sides arranged in a regular hexagonal outline. Unlike most modern diamond shapes, it belongs to neither the traditional brilliant nor step-cut family in a strict sense, hexagons can be faceted in different ways depending on the cutter’s approach. Some are step-cut with long parallel facets, others carry a modified brilliant pattern. The shape itself is the defining characteristic, not a fixed facet arrangement.

Hexagon diamonds are cut from larger rough crystals, and the yield (the percentage of rough that becomes the finished stone) tends to be lower than for more standard shapes. This contributes to their relative scarcity in the market.

They range in size from small accent stones used in cluster or pavé designs to larger center stones in statement rings, pendants, and collector pieces. The geometric regularity of the hexagon gives it a visual precision that buyers with a design-forward sensibility find particularly appealing.

How a Hexagon Diamond Is Cut and What That Means for You

Because hexagon diamonds do not follow a single standardised facet blueprint, the cutting approach matters enormously. A well-cut hexagon will have six sides of near-equal length, consistent angles at each corner, and a face-up appearance that looks balanced from every direction.

What to look for when evaluating a hexagon diamond:

• Symmetry: All six sides should appear equal in length. An irregular hexagon can look skewed or unintentional.
• Facet pattern: Ask your supplier whether the stone is step-cut or brilliant-cut. Step-cut hexagons produce long, rectangular flashes similar to an emerald cut. Brilliant-cut hexagons produce more sparkle with smaller light returns.
• Depth: Very shallow hexagons can appear glassy and lifeless. Very deep ones waste carat weight in the pavilion. A balanced depth gives the stone visual presence.
• GIA grading: Because hexagons are not covered by GIA’s standard cut grade system (which applies only to round brilliants), a GIA report for a hexagon will focus on measurements, polish, symmetry, and color and clarity grades. There is no numerical cut grade.

For step-cut hexagons specifically, clarity becomes more important, the open facets reveal inclusions more readily than brilliant-cut facets do. Aim for VS2 or better in a step-cut hexagon. Brilliant-cut hexagons offer more forgiveness at SI1 eye-clean territory.

Hexagon vs Asscher vs Emerald: Which Geometric Shape Is Right for You?

These three shapes share a geometric, architectural aesthetic. Understanding where they differ helps you make a clear choice.

The hexagon stands apart from both Asscher and emerald because it has no antecedent in Victorian or Edwardian jewelry traditions the way those shapes do. It is genuinely contemporary in feel, even when placed in a heritage-inspired setting. That combination, modern geometry with classical materials, is what makes it so interesting to serious designers.

You can read more about the Asscher cut diamond on its own page if you are comparing the two directly.

Is a Hexagon Diamond Rare?

Yes. Hexagon diamonds are significantly less common than round, oval, cushion, or emerald cut stones. There are two reasons for this.

First, the hexagon outline is not a standard shape for which most cutting facilities maintain a high-volume production process. Hexagons are cut to order or sourced as specialty stones, which means fewer of them exist in the open market at any given time.

Second, the rough diamond crystal must be assessed carefully to determine whether it can yield a well-proportioned hexagon. The yield from rough to finished hexagon is typically lower than for round or cushion shapes, which means the cost per carat reflects not just the finished stone but the rough sacrificed to get there.

If you are looking for a specific size, color grade, or clarity level in a hexagon, plan on a longer sourcing timeline than you would for standard shapes. At PASAVAJA, Heer Shah personally reviews sourcing options for specialty geometric shapes to find stones that meet the aesthetic and quality standards required for fine jewelry.

Setting Requirements for Hexagon Diamonds

Heer Shah, Director at PASAVAJA and the designer behind our bespoke commissions, works with hexagon diamonds regularly in Art Deco-inspired and minimalist settings. His perspective on how the shape behaves in real jewelry, not just on a page, informs what follows.

The six corners of a hexagon diamond are the most important practical consideration when choosing a setting. Each corner carries a degree of vulnerability, not as acute as a marquise point or a princess cut corner, but present nonetheless.

Here are the settings that work best:

Bezel setting is the most protective option and also the most architecturally appropriate for a hexagon. A full bezel wraps all six sides and corners in metal, securing the stone completely while emphasising the geometric outline. Heer Shah frequently recommends bezel settings for hexagon diamonds in bespoke commissions because they allow the hexagonal silhouette to read as a deliberate design choice rather than an accidental variation of a round or oval.

Prong setting can work on a hexagon, but requires six prongs, one at each corner, or a three-prong arrangement that catches alternate corners. A four-prong setting is not ideal because it leaves two corners unprotected. Speak with your jeweler about corner placement specifically.

Flush or gypsy setting works well for accent hexagons used in geometric pavé arrangements or pattern-based designs. This approach is common in Art Deco revival jewelry where multiple small hexagons tile together to create a honeycomb or lattice visual.

For hexagon diamonds used as center stones, platinum and 18K white gold are the most complementary metals: they do not compete with the stone’s geometric clarity. Yellow gold can work beautifully for warmer color grades (G-I range) and gives the piece a stronger Art Deco connection. Rose gold softens the geometry in an interesting way and suits buyers who want something less architectural.

Our jewelry metals guide covers the properties of each metal in more detail if you want to understand the trade-offs before choosing.

Where Hexagon Diamonds Are Used in Fine Jewelry Design

Heer Shah’s perspective on hexagon diamonds in design is straightforward: “The hexagon gives you geometry without aggression. It is precise and considered, but it does not feel sharp the way a princess cut or kite diamond does. That makes it very versatile across different jewelry contexts.”

Here is where hexagon diamonds appear most effectively:

Center stone engagement rings: A hexagon solitaire in a bezel or six-prong setting makes an immediate statement. It is immediately recognisable as a conscious design choice, not someone who wanted an oval and settled for something unusual. Buyers who choose hexagon engagement rings tend to have a clear visual sensibility and want their ring to reflect it.

Pendants: The symmetry of a hexagon reads particularly well as a pendant stone. It sits evenly on any chain orientation and requires minimal supporting design to look complete. A hexagon set in a simple bezel on a fine chain is one of the cleanest jewelry statements available.

Art Deco revival pieces: The geometric precision of the hexagon connects naturally to the Art Deco aesthetic, the movement that prioritised clean lines, symmetry, and architectural forms in jewelry design from the 1920s onward. Heer Shah incorporates hexagon diamonds in heritage-inspired commissions specifically because they honour the Art Deco vocabulary without being historical reproductions.

Geometric pavé and cluster designs: Multiple small hexagon diamonds arranged in a tessellating pattern, like a honeycomb, create a visual effect that is completely distinctive in modern jewelry design. This approach uses the hexagon’s natural geometric property: regular hexagons tile perfectly without gaps.

PASAVAJA’s Approach to Hexagon Diamond Sourcing

Sourcing hexagon diamonds requires specialist knowledge and direct access to cutters who work with specialty shapes. This is not a stone you find in standard inventory.

At PASAVAJA, we work with manufacturers and cutters who produce specialty geometric shapes specifically. When a client comes to us for a hexagon diamond, we assess the requirements in detail, target carat weight, preferred color grade, step-cut or brilliant-cut faceting, intended setting style, and then source stones that genuinely fit rather than compromising on what is available.

Heer Shah oversees all hexagon and specialty geometric diamond commissions personally. His combined expertise in diamond selection and jewelry design means that the stone we source is evaluated not just on its own merits but in the context of the finished piece it will become.

Everything we source is GIA-certified. For hexagon diamonds, the GIA report covers color grade, clarity grade, carat weight, dimensions, polish, and symmetry. We share the full report with every client before any purchase is confirmed.

We offer free worldwide shipping on all diamonds and jewelry, fully insured from point of origin to your door.

Frequently Asked Questions

Q: What is a hexagon diamond?

A: A hexagon diamond is a six-sided diamond with equal-length sides forming a regular hexagonal outline. It can be faceted in either a step-cut or brilliant-cut pattern depending on the cutter. Hexagon diamonds are specialty stones, not mass-produced, which makes them less common than round, oval, or cushion shapes.

Q: Are hexagon diamonds rare?

A: Yes. Hexagon diamonds are a specialty cut not produced in high volumes by standard cutting facilities. They require specific rough assessment and skilled cutting, and fewer exist in the open market compared to standard shapes. Sourcing a hexagon diamond often requires a longer timeline and direct access to specialist cutters.

Q: What settings work best for hexagon diamonds?

A: A bezel setting is the most protective and architecturally appropriate choice for a hexagon diamond, it secures all six corners and emphasises the geometric outline. Six-prong settings also work well. Four-prong settings should be avoided as they leave two corners unprotected.

Q: Is hexagon cut an Art Deco style?

A: The hexagon shape connects naturally to the Art Deco aesthetic, which prioritised geometric precision and symmetry in jewelry design from the 1920s onward. However, hexagon diamonds are distinctly contemporary in their current use, they reference Art Deco values without being period reproductions.

Q: How does a hexagon diamond compare to an Asscher cut?

A: Both are geometric and architectural in character, but the Asscher cut is square with clipped corners and a strict step-cut facet pattern producing concentric square reflections. Hexagon diamonds can be step-cut or brilliant-cut and have six equal sides. The Asscher has a clear historical era connection; the hexagon feels more contemporary.

Q: Is hexagon cut a step cut?

A: Not necessarily. Hexagon diamonds can be faceted as step cuts (long parallel facets, similar to emerald cut) or as brilliant cuts (triangular or kite-shaped facets radiating from the center). The shape is defined by its six-sided outline, not a single facet arrangement. Ask your supplier which faceting style a specific stone uses.
