Choose a cushion cut lab grown diamond engagement ring by comparing the actual diamond's outline, face-up dimensions and light performance before choosing carat weight or a halo setting. For a UAE purchase, confirm the centre-stone grading report, gold purity, final AED price, delivery timing and return conditions before paying.
Cushion cut buying facts at a glance
| Buying factor | What to check |
|---|---|
| Outline | Square or elongated, with balanced sides and rounded corners. |
| Visible size | Length and width in millimetres, not carat weight alone. |
| Facet appearance | Distinct flashes or a finer crushed-ice pattern, assessed in video. |
| Halo | A visible halo increases the ring's outline; a hidden halo sits below the centre. |
| Diamond weight | Separate centre-stone carat weight from total diamond weight. |
| Documentation | Check the report issuer, report number and measurements for the actual centre diamond. |
Compare cushion cut and round diamond rings
A cushion has a square or rectangular outline with rounded corners, while a round brilliant has a circular outline and a more standardised facet arrangement. Cushions vary considerably in their facet patterns, so two stones with the same weight, colour and clarity can look noticeably different.
A well-cut round brilliant typically produces strong, evenly distributed brightness. A cushion may show broader flashes or many smaller reflections, depending on its cutting style; neither the shape name nor the grading report alone establishes its visual performance.
Cushions can carry more weight below the visible top surface and may appear smaller than a round of equal carat weight. Compare actual millimetre measurements and similarly scaled photographs rather than assuming equal weight means equal finger coverage.
Choose between square and elongated cushions
Calculate the length-to-width ratio by dividing the longer measurement by the shorter one. A ratio near 1.00 indicates a square outline, while higher ratios indicate increasing elongation; there is no universal ratio that makes a cushion better cut.
Square cushions
Choose a square cushion when you want similar length and width across the finger. Check that opposite sides and rounded corners look balanced, because the outline remains visible in a solitaire and influences the shape of a fitted halo.
Elongated cushions
An elongated cushion provides more length along the finger when set vertically. Compare width as well as length: a longer stone is not necessarily larger in overall face-up area, and a narrow outline can look quite different from a broad rectangular cushion.
Ask for a straight-on video of the actual diamond rather than relying only on a setting render. Inspect the centre and ends for dark areas that remain prominent as the stone moves.
Assess sparkle, colour and clarity before carat weight
Some cushions show clearly defined facets and larger flashes; others show a crushed-ice appearance with many small, scattered reflections. These descriptions identify visual patterns, not a reliable ranking of quality.
- Light performance: Request video in diffused daylight and ordinary indoor lighting, not only jewellery spotlights.
- Transparency: Look for an overall clear appearance rather than persistent haze or dullness.
- Colour: Assess the actual stone face-up and from the side, considering how the chosen metal affects its appearance.
- Clarity: Check whether inclusions are visible without magnification and whether any near the edge require closer assessment.
VS1 is a higher clarity grade than VS2, but the difference may not be visible without magnification. An eye-clean VS2 can be a practical choice; inclusion position and the individual stone matter more than selecting a grade in isolation.
Do not use a single table or depth percentage as a pass-or-fail rule for all cushions. Measurements and proportions help you compare candidates, but they do not replace inspection of brightness, contrast and transparency.
Compare 1, 1.5, 2 and 3 carat centre stones
Carat measures weight, not visible diameter or surface area. Increasing from 1 to 2 carats does not double the diamond's length or width, and cushions of equal weight can have different dimensions.
- 1 carat: Compare the outline and band width together to judge the ring's proportions.
- 1.5 carats: Check the measurable size increase over a 1 carat candidate rather than relying on the weight difference.
- 2 carats: Inspect light performance across the larger visible surface and confirm the setting height.
- 3 carats: Pay particular attention to comfort, ring balance, prong protection and wedding-band clearance.
Keep centre weight separate from total weight when comparing prices. For example, the 3.32 ct cushion bridal set specifies a 2.00 ct centre, not a 3.32 ct centre diamond.
Match the cushion to its halo and wedding band
A solitaire leaves the cushion outline easiest to inspect, as illustrated by a 1.00 ct cushion solitaire ring. A visible halo adds a border of smaller diamonds, increasing the overall face-up outline without increasing the centre diamond's size.
Visible halo pairings
A closely fitted cushion-shaped halo follows the centre's rounded corners. For an elongated cushion, check that the halo follows its length-to-width proportions rather than making the ring look noticeably wider or squarer.
A round halo around a cushion creates a different outer silhouette and makes the centre's outline less dominant. Inspect the spacing between the centre and halo, the symmetry of the border and the colour match between the diamonds.
Hidden halos and band fit
A hidden halo sits beneath the centre and is mainly visible from the side; it does not provide the same top-view enlargement as a surrounding halo. Check side-profile images to understand its position and the height of the setting.
Ask whether your intended wedding band will sit flush without rubbing against the basket or exposed diamonds. A low setting may require a shaped band, while some raised settings allow a straight band to sit alongside.
Check gold, AED pricing and UAE purchase terms
For gold purity, 10K contains approximately 41.7% gold, 14K approximately 58.3%, and 18K 75%. Durability also depends on the alloy and ring construction, so do not choose by purity alone; confirm the options for the specific design.
Buvea Jewels is based at Office 203, Al Buteen Building 2, Gold Souk (Gate 1), Deira, Dubai, with 10K, 14K and 18K gold options depending on the ring. Buvea offers free UAE delivery in 3-5 business days and 15-day returns; check the return conditions for your selected ring before ordering.
Use the selected product's current AED price rather than a general price-per-carat estimate. A reliable comparison needs the same centre weight, dimensions, colour, clarity, gold purity and setting complexity; no live cushion-ring price is verified here.
- Request the actual centre diamond's grading report before payment.
- Every Buvea piece with a centre diamond comes with an IGI certificate for that centre diamond, plus a separate IGI report for the smaller diamonds and a gold certificate; verify the report number and match the measurements to the diamond.
- Confirm which documents cover the centre stone, smaller diamonds and gold.
- Check ring size, final payable amount and delivery address.
- Read return eligibility and any resizing or personalised-order conditions before purchase.
Frequently asked questions
What are the disadvantages of cushion cut diamonds?
Some cushions appear smaller face-up than rounds of equal weight, and their varied facet patterns make selection from specifications alone difficult. Persistent dark areas or a dull appearance are reasons to inspect an individual stone more closely, not characteristics of every cushion.
Does an elongated cushion look larger than a square cushion?
An elongated cushion looks longer, but it does not necessarily have more face-up area at the same carat weight. Compare both length and width in millimetres and view the stones at the same image scale.
How much does a 2 carat cushion cut lab grown diamond ring cost in Dubai?
There is no single price: the centre diamond's specifications, gold purity and setting affect the final AED amount. Check the current price for the exact ring and confirm that 2 carats refers to the centre stone rather than total diamond weight.
Does a halo make a cushion diamond bigger?
A visible halo makes the ring's overall face-up outline larger but does not change the centre diamond's weight or dimensions. A hidden halo mainly adds detail beneath the centre rather than a larger top-view border.
