Unique Diamond Cuts That Will Redefine What You Know

For those who seek something genuinely unique, diamonds that carry craftsmanship and sheer visual drama, the world of rare and specialty cuts offers something that other jewellery counters rarely show you. These are cuts that demand a second look. Some are inspired by cuts centuries old, born before the age of precision machinery. Others are the product of a single cutter's obsession with geometry and excellence. All of them tell a story that the round brilliant, for all its brilliance, simply cannot. 

At JANAI we offer all of the below unique Diamond Cuts for your custom engagement ring in Melbourne. Be inspired by their beauty, their story and their intricacy. Let’s begin. 

The Dutch Marquise

The Marquise is a cut that has always exhibited a certain dramatic quality. With its elongated and pointed ellipse shape commissioned by Louis XV to mirror the lips of his mistress, the Marquise de Pompadour. Yet the Dutch Marquise cut takes the drama several steps further.

The Dutch Marquise introduces a sharp hexagonal shape, featuring six straight edges forming a geometric silhouette. The stone offers a vintage appeal yet with far more complexity, and a fiery brilliant faceting arrangement. 

The Lily Cut

There’s nothing subtle about a Lily Cut diamond. This is a stone that announces itself. The Lily Cut, someones called a flower cut, arranges its facets into four symmetrical petals radiating outward from a central point. Creating a silhouette that is instantly recognisable and unlike anything else in the world. What makes this cut so unique is the softly rounded forms, together producing the floral shape that makes the Lily cut so compelling.

The four sides create a natural directionality, a diamond that can read differently depending on its orientation, giving clients flexibility in how they choose to present the stone within their custom engagement ring design

The Hexagon Cut

Geometry has always fascinated diamond cutters, and the hexagon cut is one of the more intellectually satisfying results of that fascination. A hexagon cut diamond presents six equal sides with step-cut running parallel to those sides. The overall effect is architectural rather than organic, this is a stone that feels intentionally designed. 

Because of the relatively open facet structure of the step-cut variety, a hexagon diamond showcases the diamond’s clarity in an exceptional way. Its clean symmetry and hall-of-mirrors effect creates refined understated brilliance.  

The Old Mine Cushion Cut

If any cut on this list can claim to be both rare and intimate, it is the Old Mine Cushion. Before the age of precision cutting equipment, diamonds were cut by hand. This fundamental fact shaped every aesthetic decision. Old mine cushions (produced primarily between the mid-1700s and the early 1900s) have a high crown, a small table, a large, open culet (the flat or pointed base of the stone), and a soft, rounded-square outline. Their proportions are guided more by the shape of the rough than by mathematical ideals.

Modern Old Mine Cushion Cuts are guided by the same beautiful proportions, with modern tools and cutting techniques. The consequence is a beautiful quality of light that produces a soft, pillowy radiance in a way that many consider the most beautiful effect in all of diamond cutting.

The Portuguese Cut

The Portuguese cut is, put simply, one of the most technically ambitious cuts performed on a piece of diamond rough. Developed in the early twentieth century and named in honour of the elaborate jewellery traditions of Portugal, this cut features an extraordinary number of facets. A Round typically features 156 facets compared to the 57 of a traditional round brilliant. These facets are arranged in multiple rows of both brilliant-style and step-cut arrangements, creating a stone that appears to have layers of complexity stacked upon one another.

The visual effect is unlike anything else in the diamond world. A Portuguese cut diamond does not simply reflect light; it seems to dissolve it into an almost infinite series of smaller reflections, creating an interior that shimmers a cascade of light. Because of the time and precision required, Portuguese cuts are rarely produced commercially. 

The Step Cut Pear

The Step Cut Pear shape facets run in parallel rows along the length of the stone, much as they do in an emerald cut. The result is a stone with a completely different personality, where the brilliant pear dazzles and scatters, the step cut pear is composed, deliberate, and intensely focused. Its long, linear facets act as mirrors rather than prisms, producing broad flashes of light and a window-like clarity that makes the interior of the stone visible.

The shape itself adds a further dimension. The Pear's pointed tip and edges, the most difficult part of any pear to cut without causing damage, requires particular care in a step cut, where the facets meeting at that apex must align with geometric precision. When it works, the result is a stone of remarkable elegance: the drama of the pear silhouette together with the quiet authority of the step cut.

The Moval Cut

Sitting somewhere between two beloved silhouettes, the Moval cut diamond is best understood as a hybrid between the marquise and the oval. It shares the oval’s soft curves with the marquises' elongated form and gently tapered ends. A diamond made to elongate and flatter the finger.

A Moval cut’s faceting arrangement typically follows the brilliant pattern, so it handles light with warmth and depth, but the elongated outline distributes those reflections differently, producing a distinctly graceful shimmer. The Moval cut diamond occupies a curious position in the market, not quite obscure enough to be a collector's trophy, not mainstream enough to appear in every jeweller's case. It is, in the best sense, a cut for someone who has looked at everything else and knows exactly what they want.
