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.
