Frequently Asked Questions
Is a 1 carat marquise cut Lab Grown diamond a good size for an engagement ring? +
Yes. A 1 carat marquise cut is an excellent choice for engagement rings. Its elongated,
boat-shaped outline offers strong finger coverage and a larger-looking profile while still
feeling elegant and wearable every day.
Does a 1 carat marquise cut diamond look bigger than a 1 carat round diamond? +
Yes. Marquise cuts typically appear larger face-up than round diamonds of the same carat
weight because of their elongated shape and shallow ends. This makes a 1 carat marquise look
longer and more dramatic on the finger than a 1 carat round.
What is special about the marquise cut compared to other diamond shapes at 1 carat size? +
The marquise cut is known for its elongated, pointed ends that create a slimming,
lengthening effect on the finger. It offers a mix of brilliant sparkle and bold geometry,
making it ideal for those who want something different from classic round or oval shapes.
Do 1 carat marquise cut Lab Grown diamonds sparkle as much as round diamonds? +
Marquise cuts are brilliant-cut stones, so they can be very sparkly, with plenty of fire and
brilliance. They may show a slight “bow-tie” effect across the centre, which is normal, but a
well-cut marquise will keep this subtle while maintaining strong overall sparkle.
Which colour and clarity grades are recommended for a 1 carat marquise cut Lab Grown diamond? +
Because of the elongated shape and open facets, many buyers prefer D–H colour and VVS–VS
clarity for a 1 carat marquise. This helps keep both the centre and the pointed ends looking
bright and clean to the naked eye.
Are 1 carat marquise cut Lab Grown diamonds certified by IGI or GIA? +
Yes. 1 carat marquise cut Lab Grown diamonds are often certified by IGI, GIA, and other
respected gemological laboratories. Their certificates outline the diamond’s 4Cs, proportions,
polish, symmetry, and growth method (CVD or HPHT).
Is a 1 carat marquise cut diamond practical for everyday wear jewellery? +
Yes — provided the tips are well protected. Marquise diamonds have pointed ends that should be
secured with V-prongs or a protective setting to help prevent chipping, making them suitable
for daily-wear rings, pendants, and earrings.
Which settings look best with a 1 carat marquise cut Lab Grown diamond? +
Marquise cuts look beautiful in solitaire rings, east-west settings, halos, and vintage-inspired
designs. Horizontal (east-west) marquise settings give a modern look, while classic north-south
orientations create a traditional, elongated silhouette on the finger.
Does a 1 carat marquise cut Lab Grown diamond offer good value compared to mined diamonds? +
Yes. Lab Grown diamonds already provide better value than mined diamonds, and fancy shapes like
marquise can often be more affordable per carat than round stones. This allows you to enjoy a
larger-looking, unique shape at a more accessible price point.
Is a 1 carat marquise cut Lab Grown diamond suitable for pendants and earrings as well as rings? +
Absolutely. Marquise diamonds create elegant drop pendants, modern line earrings, and stylish
studs. A 1 carat marquise centre stone works beautifully in both rings and fine jewellery pieces
where you want an elongated, graceful look.
