Cushion Cut Engagement Rings: The Complete Guide

Buying a cushion cut engagement ring often causes anxiety for UK couples who fear overpaying by 50% to 100% on high-street retail markups, or worse, receiving a poorly cut diamond that leaks light and looks dull. When you bypass traditional retail showrooms, you can secure a stunning, custom-made cushion cut engagement ring directly from a dedicated workshop, saving thousands of pounds while ensuring absolute control over the diamond's fire and brilliance. At Qutahia, we manufacture custom gold jewellery directly in our own workshop in Türkiye, offering you a straightforward, transparent path to a bespoke ring without the inflated retail price tags.

What is a cushion cut engagement ring?

A cushion cut engagement ring features a square or rectangular diamond with rounded corners and curved sides, resembling a pillow or cushion. This specific cut has been popular for over 200 years, combining the soft outline of an oval with the fiery brilliance of a modern round brilliant cut. It typically features 58 facets, which allows it to disperse light exceptionally well, making it one of the most brilliant fancy shapes available on the market today.

While older antique versions (known as old mine cuts) had steeper crowns and larger culets, modern cushion cuts are engineered for maximum light return. This blend of historical shape and modern faceting makes it a popular choice for those who value unique craftsmanship over mass-produced, standard round solitaires. You can explore our collection of custom designs in our engagement rings selection.

What are the differences between crushed ice and chunky cushion cuts?

The main difference between crushed ice and chunky cushion cuts lies in the faceting pattern on the pavilion, which determines how the diamond reflects light. A "chunky" cushion cut (often called a cushion brilliant) features distinct, larger flashes of light, similar to a round brilliant diamond, because its facets extend from the centre of the stone to the outer edges. In contrast, a "crushed ice" cushion cut (often classified as a cushion modified brilliant) has shorter, narrower facets that create hundreds of tiny, shimmering reflections resembling crushed ice in a glass.

Approximately 70% of modern cushion cut diamonds on the market are modified brilliant "crushed ice" cuts because this faceting pattern allows diamond cutters to retain more weight from the rough stone, reducing the cost per carat. Chunky cushion cuts are rarer and typically carry a premium of 5% to 15% due to the higher waste of rough diamond material during the cutting process. If you prefer a distinct, classic look, a chunky cut is ideal, whereas those seeking a modern, glittering shimmer often prefer the crushed ice variant.

How do you choose the right length-to-width ratio for a cushion cut diamond?

You choose the right length-to-width ratio for a cushion cut diamond by deciding whether you prefer a perfectly square shape, which requires a ratio between 1.00 and 1.05, or an elongated shape, which typically requires a ratio between 1.10 and 1.20. A ratio of 1.00 represents a perfect square, while a ratio of 1.15 produces a distinct rectangular silhouette that can make the wearer's finger appear longer and more slender.

Elongated cushion cut diamonds are highly sought after but represent only about 20% of all cushion cuts produced, making them harder to find in specific colour and clarity combinations. When designing a bespoke piece with bespoke engagement ring makers UK, selecting the ratio is one of the first steps in personalising the overall look of the ring. It is important to note that elongated cushions often show more colour in their corners, so choosing a slightly higher colour grade (such as F or G) is recommended for these shapes.

How much does a cushion cut engagement ring cost in the UK?

A custom cushion cut engagement ring in the UK typically costs between £1,200 and £8,000, depending on whether you choose a lab-grown or natural diamond, the carat weight of the stone, and the gold purity of the band. Choosing a 1.00-carat lab-grown diamond in a solid 18ct gold solitaire setting generally ranges from £1,500 to £2,500, whereas a natural diamond of the same size and quality can cost between £4,500 and £7,500.

By working directly with a workshop rather than a traditional high-street retailer, you eliminate middleman markups, which often add 40% to the final price. Our pieces are produced directly in our Türkiye workshop, allowing us to pass these savings directly to you. To help you plan your budget, we offer clear pricing structures across 9ct, 14ct, and 18ct gold, ensuring you know exactly where your money is going without any hidden showroom overheads.

How do you choose between a natural and lab-grown cushion cut diamond?

You choose between a natural and lab-grown cushion cut diamond by balancing your budget against your personal values regarding stone origin, as both options are physically, chemically, and optically identical. A lab-grown diamond offers a price saving of approximately 60% to 80% compared to a natural diamond of the same carat weight, colour, and clarity. This price difference allows couples to purchase a significantly larger centre stone, such as a 2.00-carat lab-grown diamond, for less than the cost of a 1.00-carat natural diamond.

For those who prefer the traditional appeal of a gemstone formed deep within the earth over billions of years, a natural diamond remains the preferred choice. For those looking to maximise their budget without compromising on the diamond's brilliance, our lab-grown diamond engagement rings collection offers a high-quality, modern alternative. Every larger centre stone we supply, whether natural or lab-grown, is accompanied by an independent, internationally recognised certification from the GIA or IGI.

Which metal setting is best for a cushion cut diamond ring?

The best metal setting for a cushion cut diamond ring is 18ct yellow gold or platinum for maximum durability, though 18ct white gold and 14ct gold also offer excellent protection for the stone's rounded corners. Because cushion cut diamonds have slightly exposed corners compared to round brilliant diamonds, a secure four-prong or double-prong setting is highly recommended to protect the stone from accidental knocks during daily wear.

If you choose a white diamond with a colour grade of H or lower, setting it in 18ct yellow gold can mask slight warm undertones, making the diamond appear whiter. Conversely, if you select a high-colour diamond (D to F), a white metal like 18ct white gold or platinum will enhance its icy brilliance. All of our custom gold bands are produced in our workshop in accordance with REACH nickel-release standards, ensuring they are suitable for those with sensitive skin.

How does the Qutahia custom design process work?

The Qutahia custom design process works by collaborating directly with our workshop team to design your ring digitally before we begin the physical handcrafting process. You start by sharing your design ideas, preferred gold purity (9ct, 14ct, or 18ct), and diamond specifications during a straightforward digital consultation. Once the design is finalised, our master craftspeople in Türkiye handcraft your piece, stamping it with its gold fineness mark (375 for 9ct, 585 for 14ct, or 750 for 18ct) directly in our workshop.

Our lead time is 10-14 days for simpler designs (such as a classic solitaire or standard pavé band) and 4-6 weeks for more complex commissions (such as intricate settings, less common stone shapes or sizes, or fully bespoke designs), with separate postage time required on top of either making period. For clients who prefer to collect their finished piece in person, secure collection can be arranged by appointment at our UK operations partner, Big Gold Jewellery, 51 Jameson Street, Hull HU1 3JA.

Frequently Asked Questions

Do cushion cut diamonds look smaller than round diamonds?

Yes, cushion cut diamonds generally look slightly smaller than round diamonds of the same carat weight because they are cut deeper and have more of their weight distributed in the bottom half (pavilion) of the stone. A 1.00-carat cushion cut diamond typically has a surface area that is roughly 10% smaller than a 1.00-carat round brilliant diamond.

What is the best clarity grade for a cushion cut engagement ring?

The best clarity grade for a cushion cut engagement ring is typically VS2 or SI1, as these grades offer an "eye-clean" appearance where inclusions are invisible to the naked eye, saving you money compared to flawless grades. Because cushion cuts have a large open table, it is important to verify that any inclusions are located near the edges rather than directly under the centre table.

Are Qutahia rings hallmarked by a UK Assay Office?

No, Qutahia pieces are made in our own workshop in Türkiye and carry a gold fineness stamp (375 for 9ct, 585 for 14ct, 750 for 18ct) rather than a UK Assay Office hallmark. This direct workshop stamping process allows us to maintain our streamlined, online-first model while guaranteeing the exact gold purity of every piece we create.

What warranty is provided with a Qutahia engagement ring?

Every Qutahia piece comes with a 1-year repair & resizing warranty, which covers any manufacturing defects and provides one free resizing within the first twelve months of ownership. This warranty ensures your ring fits comfortably and remains in perfect condition, backed directly by our workshop team.

Are smaller diamonds in Qutahia rings certified?

Yes, while larger centre stones come with internationally recognised, independent certification (GIA/IGI), smaller diamonds used in our pavé bands and halo settings are certified via Qutahia's own internal certification process. This dual-track certification ensures that every single stone in your ring, regardless of size, meets our strict standards for colour, clarity, and cut.

Can I collect my ring in person in the UK?

Yes, you can collect your finished ring in person by booking a secure appointment at our UK operations partner, Big Gold Jewellery, 51 Jameson Street, Hull HU1 3JA. This option is perfect for clients who prefer not to have high-value jewellery delivered to their home address.

Does a cushion cut diamond hide inclusions well?

No, a cushion cut diamond does not hide inclusions as easily as a round brilliant cut due to its large table facet, which acts like a window into the centre of the stone. However, modified brilliant cushion cuts with a crushed ice appearance are slightly better at concealing small inclusions than chunky cushion cuts due to their highly active, shimmering light patterns.

What colour grade is recommended for a cushion cut diamond?

The recommended colour grade for a cushion cut diamond is G or H for white gold or platinum settings, and I or J if you plan to set the stone in yellow gold. Because cushion cuts tend to retain and show body colour more than round diamonds, choosing a grade lower than J is generally not advised unless you prefer a warm, champagne hue.

Because we operate a dedicated, workshop-direct model rather than a mass-production factory, we limit our custom commission capacity each month to ensure every piece receives the focused attention of our master jewellers.
