If you’re in the market for a ring that merges timeless romance with modern sparkle, then a cushion-cut diamond ring is an excellent choice. And if you browse the collection at C6 Diamonds, you’ll see why this shape is poised to dominate in 2026. Here’s a deep dive into the rise of the cushion cut, what to look for, and the top styles you’ll want to consider.

Why the Cushion Cut Is “It” for 2026

The cushion cut — often described as a “pillow” shape diamond, with soft rounded corners and broad facets — has a heritage look, yet it delivers outstanding brilliance. According to expert guides, its distinct soft square or rectangular outline with rounded edges gives it a timeless, romantic aesthetic. 

More importantly, jewellery trend-reports forecasting 2026 place cushion cuts firmly among the most sought-after engagement styles. For example, one major Australian fashion site lists cushion cut as part of “10 styles you’ll see everywhere in 2026”. And another guide notes that while round and oval still dominate, “more unique cuts like cushion … are growing in popularity” going into 2026. 

In short: the cushion cut offers a blend of vintage charm + modern sparkle, and 2026 is the year it truly becomes a mainstream favourite.

What to Look For: Key Specifications of Cushion Cut Diamonds

Before you dive into specific ring styles, there are a few technical considerations that will help you pick a high-quality piece.

• Proportions (depth/table): For cushion cuts, an ideal depth and table are generally under 70 % each to avoid a “dead” look with less brilliance. 
• Colour & Clarity: Because cushion cuts tend to show colour more than some other shapes (due to their large facets), aim for higher colour grades (e.g., H or better) and clarity grades that ensure they are “eye-clean”.
  
• Faceting style: Cushion cuts come in different facet patterns (e.g., “classic” vs “crushed ice”). Luxury guides note that this influences how the diamond sparkles.
• Setting & metal: The setting style (halo, solitaire, three-stone) and metal (white gold, rose gold, yellow gold, platinum) will affect how the stone appears on the finger and what kind of “vibe” the ring gives.
  

When you visit C6 Diamonds’ cushion-cut ring collection, keep these specs in mind so you select not just a beautiful ring — but a quality one.

Top Cushion Cut Ring Styles for 2026

Here are the most compelling styles for 2026 — all of which you will find (or can ask for) at C6 Diamonds 

1. Solitaire Cushion Cut Ring

One of the most timeless styles: a single cushion-cut diamond set in a clean band (metal of your choice). This lets the diamond be the star. For 2026, minimal bands with slender profiles are in vogue, allowing the cushion cut to shine.

Why it works in 2026: Trend guides emphasise that simplicity and focus on the stone are coming back. With cushion cuts' vintage charm + modern execution, a clean solitaire lets the shape speak.

Styling tip: Choose a band metal that flatters your skin tone (rose/ yellow gold for warmer tones, white/ platinum for cooler tones). And ask how the prongs are set: four or six-prong styles influence visibility and elegance.

2. Halo Cushion Cut Ring

A halo setting (i.e., small diamonds encircling the centre stone) remains a strong favourite. For cushion cuts, the halo accentuates the soft curves and boosts sparkle.

Why it’s trending: The halo effect adds drama and size illusion, which aligns with 2026’s push toward distinctive expressions in engagement rings. Vintage revival is strong, and halo settings nod to the heirloom aesthetic. 

Styling tip: For a cushion-cut with a halo, make sure the halo diamonds are proportionate to the centre stone. Too large can overpower the cushion shape; too small may get lost.

3. Three-Stone or Side-Stone Cushion Cut Ring

Another option: a cushion-cut centre with two flanking diamonds or coloured gemstone side stones. This style adds dimension and tells a story (past-present-future).

Why it’s relevant: Trend commentary for 2026 notes that mixing shapes (e.g., cushion centre with baguette or emerald sides) is part of the jewellery forward-thinking movement. 

Styling tip: When you visit C6 Diamonds, ask about matching the side-stones’ colour/clarity to the centre stone so you maintain visual harmony.

4. Vintage-Inspired Cushion Cut Ring

This is perhaps the most exciting category for 2026: cushion cuts with milgrain detailing, filigree designs, yellow gold bands, or “old mine-style” proportions. These rings channel nostalgia and craftsmanship.

Why it’s on-trend: Articles consistently pinpoint an increased demand in vintage-aesthetic jewellery, and the cushion cut is a natural fit — the shape itself hails from historical cuts (“old mine”, “mine cut”).

Styling tip: Yellow or rose gold tend to complement the vintage aesthetic. If you love detail, look for gallery work (the side view of the ring) with openwork or milgrain edges. At the same time, make sure the setting still protects the cushion diamond securely.

5. Elongated/Rectangular Cushion Cut Ring

While many cushion cuts are square, there is a rising interest in the elongated rectangular cushions — they lend a slimming effect to the finger and appear larger face-up.

Why it’s emerging: One 2025-26 trend forecast notes “a surge in demand for elongated cushion cuts … unique, eye-catching rings that remain cost-effective”. 

Styling tip: For elongated cushions, check the length-to-width ratio (ideally around 1.10 to 1.30 depending on your preference). Also ensure the setting mounts the stone in a way that protects the corners from chipping.
