Cushion Cut Engagement Rings | 2025’s Trending Diamond Shape in Hong Kong
Looking for a diamond that’s not basic, gives off royal energy, and makes you feel like a vintage-glam goddess or modern-day rebel? Let us introduce you to the cushion cut, the quiet powerhouse of the diamond world that’s making a major comeback in 2025 engagement rings.
At Valentina Fine Jewellery, we specialise in bespoke diamond rings handcrafted in Hong Kong, and the cushion cut is hands-down one of our favourite shapes to work with this year and one of the most requested. Here’s why it’s trending and why you just might fall in love with it too.
🔍 So, What Exactly Is a Cushion Cut Diamond?
Think of it as a square or rectangular diamond with pillowy, curved corners, like a diamond and a cloud had a beautiful baby. The cushion cut has been around for over 200 years, but don’t let the history fool you, it’s anything but dated.
You’ll often hear it called an “antique cut” or “pillow cut,” and it’s got that old-money sparkle meets modern cool energy that so many of our Hong Kong brides are after in 2025.
✨ Square vs. Elongated Cushion Cuts
One of the best things about cushion cuts? You’ve got options.
Square cushions (1:1 ratio) feel soft, symmetrical, and vintage-inspired.
Elongated cushions (1.15–1.30+ ratio) look bigger face-up and give your finger a long, lean look.
Both are stunning, it’s all about your style and what flatters your hand.
💎 Brilliant vs. Crushed Ice vs. Antique Cushion Cuts
Here’s where it gets juicy. Cushion cuts come with different “personalities” depending on the cutting style:
Brilliant Cut Cushion – Big, chunky facets. Maximum sparkle. Often called a “modern cushion.”
Crushed Ice Cushion – Tiny facets that scatter light like glitter. Think extra sparkle with mystery vibes.
Antique Cushion / Old Mine Cut – Hand-cut with larger facets, open culet, and romantic charm. It’s got that “found in a Parisian flea market” energy we live for.
Each style creates a totally different vibe, so we always recommend seeing a few to decide which one is right for you.
💥 Why Cushion Cuts Are Trending in 2025
Cushions are having a full-blown moment this year, and it’s not hard to see why. In a sea of round and oval diamonds, the cushion cut feels fresh, unique, and unapologetically elegant.
They’re popping up on celebrity fingers, in fashion editorials, and most importantly — in our clients’ engagement custom rings and jewellery. The requests for cushion cuts in Hong Kong have doubled this year alone.
📐 Ideal Proportions (But Let’s Not Obsess)
Sure, you can aim for a perfect 1.08 length-to-width ratio and ultra-symmetrical pavilion angles, but remember: diamonds aren’t just numbers.
While we’ll always guide you toward a beautifully cut stone with good polish and symmetry, we also believe the sparkle test and face-up appeal matter more than stats on the GIA certificate paper.
Cushion cuts are especially tricky, two diamonds with the same carat and specs can look completely different. That’s where our expertise comes in 😉
💍 Best Setting Styles for Cushion Cut Engagement Rings
Cushions play well with just about any style, but here are our favourite combos:
- Classic Solitaire – Let the diamond do the talking. Clean, elegant, timeless.
- Hidden Halo – Subtle sparkle that frames your stone from below. Sneaky and sexy.
- Double Claw Prongs – A vintage-inspired detail that looks luxe and protects those rounded corners.
- Trilogy Ring – Adds finger presence, especially gorgeous with elongated cushions, there are many options of side diamonds to choose from.
- Bezel Setting – Sleek and modern, ideal for active hands and low-maintenance sparkle.
Oh, and we can custom-make any of these in 18k gold or platinum, or both. Your ring, your rules.
💡 Expert Tips from a GIA Diamond Specialist
1. Cushion cuts tend to hide inclusions well, so you can usually go lower on clarity (SI1 or even SI2 in some cases).
2. They also mask colour more than most shapes — an H or even I colour can still look icy-white in the right lighting, plus we recommend setting the diamond in platinum to make it "pop".
3. Always ask to see the diamond loose, and if possible in daylight, not just under dazzling store lights.
This is where working with a specialist (hi 👋) can save you from expensive mistakes and help you score the best sparkle for your budget.
Fun Fact: Cushion cuts were the go-to shape in the 1800s and early 1900s before round brilliants took over. That means many antique rings you see from the Art Deco or Victorian eras?
Yep, cushion cut magic.
