An elongated Old Mine cushion often draws you in with broad flashes, a raised crown and a small open centre. A modern elongated cushion can have a finer, more closely divided sparkle, or a bold pattern of its own. Both have the long outline and softened corners that make a cushion so easy to imagine on a hand.
The choice becomes personal when you see them move. You may find yourself waiting for one large facet to catch the light, or enjoying a scattering of smaller reflections with every gesture. Try both in the light you live in, then notice which one you want to see again.
The same long shape, a different first impression
Picture a simple ring with the diamond running along the finger. An elongated cushion gives you rounded corners within a rectangular outline. The amount of curve changes the feeling: fuller shoulders can make a stone look pillowy; straighter sides can give it a more defined shape.
That outline and the cutting style are separate choices. An Old Mine can be nearly square or clearly elongated. Modern cushions vary in length too. Begin with the shape you enjoy on your own hand, then look into the diamond.
The 5.03 Ct. F VS1 Old Mine Cushion measures 11.72 × 8.91 mm, a length-to-width ratio of 1.32. The 3.09 Ct. F SI2 Old Mine Cushion measures 10.21 × 8.10 mm, a ratio of 1.26. Those numbers describe the length relative to the width; the photographs show the curves.
The broad reflections of an Old Mine cushion
There is time to follow individual facets in an Old Mine cushion. A broad reflection may brighten beside the centre, darken as you turn your hand, then return from another angle. If you enjoy looking closely at a diamond, that changing pattern can be part of the pleasure of wearing it.
Old Mine cuts typically have a smaller table, higher crown, short lower-half facets and a visible culet, the small flat facet at the bottom of the stone. Seen through the top, the culet can look like an opening at the centre. These are characteristic features of the style, described in GIA’s Old Mine guide. Individual stones vary.
The 3.09 Ct. F SI2 Old Mine Cushion has a more prominent open centre in its face-up photograph. Seeing both helps you decide how much of that detail you enjoy. Even within the Old Mine family, your preference can be quite specific.
Two 5.03 carat cushions in motion
These two diamonds bring the comparison closer in weight and outline. Both weigh 5.03 ct. Imperial's Old Mine cushion has a 1.32 length-to-width ratio; the contemporary cushion brilliant shown by Diamonds By Lauren is about 1.30. The second stone is lab-grown and is identified that way throughout this comparison. Its video is an archival example from the seller, whose listing is marked sold.

The clips were made separately, with different lighting, backgrounds and magnification. Their displayed sizes do not represent the diamonds at the same scale. Use them to follow the facet patterns and the shape of the centre as each stone turns. A brighter frame in one clip cannot establish which diamond would look brighter beside the other. The stones also differ in origin, colour and clarity.
| Detail | Imperial Old Mine | Contemporary lab-grown cushion |
|---|---|---|
| Weight | 5.03 ct | 5.03 ct |
| Face-up size | 11.72 × 8.91 mm | 11.42 × 8.78 mm |
| L/W ratio | 1.32 | 1.30 |
| Table | 47% | 60% |
| Total depth | 69.1% | 69.5% |
| Colour and clarity | F VS1 | G VVS2 |
Their similar weight and ratios make the table-size difference easier to understand. The Old Mine's 47% table leaves a larger share of the face occupied by surrounding crown facets; the contemporary example has a 60% table. Those percentages describe two particular diamonds. Read them with the profile and moving image before drawing a conclusion about their appearance. Figures come from Imperial's stone dossier and the linked seller's listing.
Why crushed ice is our least favourite cushion look
Modern elongated cushions include several facet patterns. Some retain larger, clearly separated reflections. Others show the dense, fine texture called crushed ice, described in GIA’s guide to diamond shapes. Crushed ice is the cushion look we find least attractive.
To our eye, that crowded glitter can look fussy and visually muddled. Small reflections compete across the face, making it harder to enjoy a clear pattern. The outline may be beautiful; the fragmented interior is where it loses us.
We find the broad flashes of an Old Mine much more beautiful. You can follow the larger reflections as your hand turns, see the open culet, and enjoy the way the pattern changes around it. Those are the details we would want to keep looking at in a ring of our own.
Modern cushions include brilliant and modified brilliant arrangements. GIA describes variations with four or eight pavilion mains, and modified designs with additional facets. The term “modern elongated cushion” covers several appearances. See GIA’s explanation of cushion cutting styles.
What to look at together
| Detail | Elongated Old Mine cushion | Modern elongated cushion |
|---|---|---|
| Reflections | Often broad, with individual facets easy to follow. | Watch the contemporary 5.03 ct example above, then the crushed-ice example. Modern cushions cover several facet patterns. |
| Centre | A visible culet is characteristic; its size varies. | Look for the central pattern as the stone turns. Compare it with the open culet visible in the Old Mine video. |
| Profile | A raised crown is typical and can be part of its appeal. | Profiles vary with the design. View the stone from the side. |
| On the hand | Judge the actual length, width, curves and movement. | Use the same checks, at a similar scale and in similar light. |
For a close decision, ask to see both stones together in diffuse daylight and ordinary room light. Include a slow turn, a face-up pause and a side view. Then look at each from a comfortable viewing distance. Separate photographs are useful introductions; a shared view makes differences in size and light easier to judge.
Imagine the ring you would wear
A plain band leaves the outline easy to see. A bezel traces its curves; prongs leave more of the sides visible. With an Old Mine cushion, a side view also lets you enjoy the raised crown. Ask the jeweller to plan the setting around the diamond’s depth, corners and girdle condition.
If an antique history is part of the attraction, ask for the evidence for the particular stone. Cutters also make Old Mine-style diamonds today, as GIA explains. The name describes a cutting style; a documented history adds something separate to the choice.
