About 1 Carat Cushion Cut Lab Grown Diamonds
1 Carat Cushion Cut Lab Grown Diamonds – Soft Elegance with Brilliant Depth
A 1 carat cushion cut lab grown diamond offers vintage-inspired charm with modern brilliance. Known for its soft, rounded corners and deep, radiant sparkle, the cushion cut combines timeless beauty with contemporary appeal. For UK customers seeking a diamond that feels romantic, expressive and luxuriously detailed, a 1 carat cushion cut stone delivers an elegant and captivating presence.
Created using advanced CVD and HPHT technology, lab grown diamonds share the same chemical composition, durability and optical performance as mined diamonds. At Variation, each 1 carat cushion cut diamond is IGI-certified and hand-selected for symmetry, clarity and superior light performance — ensuring brilliance with responsible, sustainable craftsmanship.
Why Choose a 1 Carat Cushion Cut Diamond?
The cushion cut combines the brilliance of a round diamond with the soft geometry of a square or rectangular shape. Its larger facets create a glowing “crushed ice” or “antique” sparkle, depending on the cut style, making it a favourite among UK jewellery buyers.

Frequently Asked Questions
Is a 1 carat cushion cut lab grown diamond a good size for an engagement ring? +
Yes. A 1 carat cushion cut is a classic, versatile size that offers a balanced look on most
hands. It feels substantial without being too large and works beautifully in solitaire, halo,
and vintage-inspired engagement ring designs.
Does a 1 carat cushion cut look smaller than a 1 carat round diamond? +
Cushion cuts typically have a slightly smaller face-up area than round diamonds of the same
carat weight due to deeper proportions. However, their soft square or pillow shape, rounded
corners, and scintillating sparkle still give a very elegant, noticeable presence on the hand.
What is special about the cushion cut compared to other shapes at 1 carat size? +
Cushion cuts blend vintage charm with modern brilliance. They feature rounded corners and
a “pillow” outline, with either chunkier antique-style facets or more modern brilliant faceting,
giving a romantic, soft look that many people prefer over sharper geometric shapes.
Do 1 carat cushion cut lab grown diamonds sparkle as much as round diamonds? +
Cushion cuts can be very sparkly, especially in modern brilliant-style versions, but they
typically show a slightly softer, more romantic sparkle than round diamonds. Round cuts still
maximise overall light return, while cushions offer character and depth.
Which clarity and color grades are ideal for a 1 carat cushion cut lab grown diamond? +
Cushion cuts can hide some inclusions better than step cuts but may show color slightly more
near the corners and edges. Many buyers prefer D–H color and VVS–VS clarity for a bright,
eye-clean 1 carat stone, especially in Lab Grown diamonds where higher grades are more accessible.
Are 1 carat cushion cut lab grown diamonds certified by IGI or GIA? +
Yes. 1 carat cushion cut Lab Grown diamonds are commonly certified by IGI, GIA, and other
recognised gemological laboratories, with full grading for cut, color, clarity, carat weight,
and growth method.
Is a 1 carat cushion cut lab grown diamond suitable for everyday wear jewellery? +
Absolutely. Cushion cuts have no sharp points, which makes them slightly less prone to chipping
than shapes like princess or marquise. In a secure setting, a 1 carat cushion is ideal for
everyday engagement rings, pendants, and stud earrings.
Does a 1 carat cushion cut lab grown diamond offer good value for money? +
Yes. Cushion cuts usually cost less per carat than round diamonds, and Lab Grown diamonds are
more accessible than mined. Together, this makes a 1 carat cushion cut Lab Grown diamond an
excellent value with strong visual impact and distinctive style.
Which settings look best with a 1 carat cushion cut lab grown diamond? +
Cushion cuts shine in halo, solitaire, double-halo, vintage-inspired, and pavé band settings.
Halos can make a 1 carat cushion appear larger, while simple solitaires highlight the diamond’s
shape and faceting without distraction.
Do 1 carat cushion cut lab grown diamonds come in different facet styles and ratios? +
Yes. Cushion cuts are available in chunkier antique-style facets, modern brilliant or crushed-ice
patterns, and with squarer or more elongated ratios. This lets you choose the exact look and
personality you want, even at the same 1 carat weight.
