Frequently Asked Questions
Is a 1 carat radiant cut lab grown diamond a good size for an engagement ring? +
Yes. A 1 carat radiant cut diamond is an excellent choice for engagement rings. Its rectangular or
square outline with trimmed corners offers strong presence, while the brilliant-style faceting creates
intense sparkle that looks beautiful in both classic and modern settings.
Does a 1 carat radiant cut diamond look larger than a 1 carat round or cushion diamond? +
A radiant cut often appears slightly larger than a cushion of the same weight and can look similar in
size to a round, depending on proportions. Elongated radiants, in particular, provide more finger
coverage and a visually larger look at the 1 carat size.
What is special about the radiant cut compared to emerald or princess cuts at 1 carat size? +
Radiant cuts combine the outline of emerald or princess cuts with brilliant-style faceting. This means
you get a modern geometric shape plus strong sparkle similar to a round. The cut corners also make it
more durable than sharp-cornered princess cuts in everyday wear.
Do 1 carat radiant cut lab grown diamonds sparkle as much as round diamonds? +
Radiant cuts are designed with many facets to maximise brilliance and fire. While round diamonds remain
the benchmark for overall light return, a well-cut 1 carat radiant cut can be extremely sparkly with a
rich, crushed-ice or kaleidoscopic effect.
Which color and clarity grades are recommended for a 1 carat radiant cut lab grown diamond? +
Radiant cuts can show color slightly more in the corners and along the edges. Many buyers choose
D–H color and VVS–VS clarity for a bright, clean look at 1 carat, especially
if they prefer a whiter, high-contrast appearance in white metals like platinum or white gold.
Are 1 carat radiant cut lab grown diamonds certified by IGI or GIA? +
Yes. Radiant cut lab grown diamonds are commonly certified by IGI, GIA, and other internationally
recognised laboratories. The certificate will list the diamond’s 4Cs, proportions, polish, symmetry,
and growth method (CVD or HPHT).
Is a 1 carat radiant cut diamond durable enough for everyday wear in a ring? +
Yes. The trimmed corners of the radiant cut reduce the risk of chipping compared to sharp-cornered
shapes like princess cuts. In a secure prong or bezel setting, a 1 carat radiant cut is well-suited
for daily-wear engagement rings and fine jewellery.
Which settings look best with a 1 carat radiant cut lab grown diamond? +
Radiant cuts look beautiful in solitaire settings, halos, three-stone rings, and contemporary east-west
designs. Their straight edges pair well with tapered baguettes, trapezoid side stones, and pavé bands,
creating a luxurious and structured look.
Does a 1 carat radiant cut lab grown diamond offer good value compared to mined diamonds and round cuts? +
Yes. Lab grown diamonds generally cost less than mined diamonds, and radiant cuts are often priced
below round cuts per carat. This makes a 1 carat radiant cut lab grown diamond an excellent value for
those who want strong sparkle and a modern shape at a more accessible price point.
Do 1 carat radiant cut lab grown diamonds come in different ratios and styles (square vs elongated)? +
Yes. Radiant cuts are available in squarer ratios that resemble princess cuts, as well as elongated
rectangular profiles similar to emerald cuts. This allows you to choose a compact, modern look or a
more slender, elongated silhouette while staying at the 1 carat weight.
