Choosing between a cushion cut and a round brilliant diamond is one of the most important decisions when selecting an engagement ring. Both are iconic, but they offer completely different expressions of light, style, and personality. This guide breaks down everything you need to know to make the right choice.
Round Brilliant Diamond — Maximum Sparkle & Timeless Perfection
The round brilliant diamond is engineered for one purpose: maximum light performance.
With 58 precisely calculated facets, the round cut delivers unmatched brilliance, fire, and scintillation. It is the most widely chosen diamond shape in the world and remains the benchmark of timeless elegance.
Why buyers choose round diamonds:
- Highest brilliance among all diamond shapes
- Perfect symmetry and light reflection
- Strong resale value and global demand
- Universally flattering on any hand shape

The History of the Round Brilliant Diamond
The round brilliant cut as we know it today was perfected in 1919 by mathematician Marcel Tolkowsky, who calculated the precise angles and proportions needed to maximise a diamond’s light return. Before Tolkowsky’s breakthrough, diamonds were cut by intuition rather than science. His work transformed diamond cutting into an exact discipline — and the round brilliant has remained the world’s most popular diamond shape for over a century. Its enduring appeal lies not just in its beauty, but in the mathematical perfection behind every facet.
Cushion Cut Diamond — Romantic, Vintage & Distinctive
The cushion cut diamond blends a square silhouette with softened corners, creating a romantic, pillow-like appearance that has captivated jewelry lovers for centuries.
Unlike the sharp brilliance of a round diamond, cushion cuts produce a softer, more candlelight-like glow — giving them a unique emotional warmth that feels both intimate and luxurious.
Why buyers choose cushion cuts:
- Vintage-inspired luxury aesthetic
- Larger visual appearance per carat
- Softer, romantic sparkle perfect for candlelight
- More distinctive than the classic round shape
The History of the Cushion Cut Diamond
The cushion cut has roots stretching back to the 18th century, when it was known as the “old mine cut” — the dominant diamond shape before modern cutting technology existed. Old mine cuts were hand-cut by candlelight, which is why cushion diamonds produce that distinctive soft, warm glow rather than the sharp brilliance of modern cuts. Throughout the Victorian and Edwardian eras, cushion cuts adorned the rings of royalty and aristocracy across Europe. Today, the cushion cut has experienced a powerful revival among brides who want a ring with history, romance, and a sense of timeless individuality.
Which Ring Setting Suits Each Diamond Shape?
The diamond shape you choose will influence which setting styles work best. Here is a guide to the most flattering combinations:
Round Brilliant Diamond — Best Settings:
- Solitaire — The classic choice. A single round brilliant in a four or six-prong setting allows maximum light to enter the stone from all angles.
- Pavé or Halo — Surrounding the centre stone with smaller diamonds amplifies its brilliance and creates a larger visual impact.
- Three-Stone — A round brilliant centre flanked by two side stones is one of the most meaningful and elegant combinations in fine jewelry.
Cushion Cut Diamond — Best Settings:
- Halo — A halo of small round diamonds around a cushion cut creates a vintage, glamorous look reminiscent of Art Deco jewelry.
- Bezel — A sleek metal bezel encircling the cushion cut gives a modern, architectural feel while protecting the stone’s soft corners.
- Split Shank — A band that splits as it approaches the centre stone adds drama and visual width, complementing the cushion’s larger face-up appearance.
How to Stack and Pair Your Engagement Ring with a Wedding Band
Choosing the right wedding band to complement your engagement ring is just as important as the ring itself. Here is how each diamond shape pairs best:
Round Brilliant Diamond:
The symmetrical profile of a round brilliant pairs beautifully with almost any wedding band style. A simple polished band in matching metal is always elegant. For more sparkle, a diamond eternity band or a curved ‘shadow’ band that nestles against the engagement ring setting creates a seamless, unified look.
Cushion Cut Diamond:
Because cushion cut settings often sit slightly higher on the finger, a contoured or curved wedding band works best — it sits flush against the engagement ring without leaving a gap. A vintage-inspired milgrain band or a delicate pavé band in rose gold complements the cushion cut’s romantic aesthetic perfectly.
General Stacking Tips:
- Match metal colours for a cohesive look, or intentionally mix rose gold and white gold for a modern contrast stack
- Consider a ‘nesting’ band custom-made to fit your specific engagement ring setting
- If you plan to stack multiple bands, choose a lower-profile engagement ring setting to keep the overall look balanced

Which Diamond Shape Should You Choose?
The right diamond shape comes down to your personal style and what you want your ring to say about you.
- Choose a round brilliant diamond if you want maximum sparkle, timeless appeal, and a ring that will never go out of style.

Frequently Asked Questions
Is a cushion cut or round diamond more expensive?
Round diamonds typically cost more per carat because the cutting process wastes more rough stone. Cushion cuts offer excellent value while maintaining a luxurious appearance.
Which diamond shape looks bigger?
Cushion cuts tend to have a larger face-up appearance per carat compared to round diamonds, making them appear bigger at the same carat weight.
Which shape holds its value better?
Round brilliant diamonds generally have stronger resale value due to their universal demand. However, the best investment is always a diamond you love wearing every day.
Can I customize the diamond size for either shape?
Yes — at JewelryRich, all engagement rings are fully customizable. Contact our team to discuss your ideal specifications.
Which diamond shape is better for small hands?
Round brilliants are universally flattering on all hand sizes. Cushion cuts, with their larger face-up appearance, can make fingers appear slightly shorter — though this is largely a matter of personal preference.
Can I pair a cushion cut with a round brilliant wedding band?
Yes — mixing diamond shapes in a bridal stack is a popular modern trend. A curved pavé band with round brilliant diamonds pairs beautifully with a cushion cut centre stone.
