Frequently Asked Questions
Is a 1 carat Princess Cut Lab Grown diamond a good size for an engagement ring? +
Yes. A 1 carat Princess Cut Lab Grown diamond is a classic, versatile size for engagement rings.
The square outline gives a modern, structured look with strong finger coverage while still being
comfortable for everyday wear.
Does a 1 carat Princess Cut diamond look smaller than a 1 carat Round diamond? +
Princess Cuts can appear very similar in face-up size to Rounds, though Rounds may look slightly
larger due to the way light is distributed across the circular outline. The crisp square shape
of a Princess Cut creates a different visual impression – more angular and contemporary.
What is special about the Princess Cut at the 1 carat size? +
The Princess Cut combines strong brilliance with a sharp square or slightly rectangular outline.
At 1 carat, it offers a bold yet refined presence, with a geometric look that suits modern,
minimal, and classic designs equally well.
Do 1 carat Princess Cut Lab Grown diamonds sparkle as much as Round diamonds? +
Princess Cuts are brilliant-cut diamonds, so they can be very sparkly with plenty of fire and
scintillation. Round diamonds still maximise all-round light return, but Princess Cuts offer a
more directional, angular sparkle that many people love for its modern character.
Which colour and clarity grades are ideal for a 1 carat Princess Cut Lab Grown diamond? +
Princess Cuts can hide some inclusions thanks to their brilliant faceting, but the corners and
table should still look clean to the eye. Many buyers prefer D–H colour and VVS–VS clarity in
the 1 carat range for a bright, crisp, eye-clean appearance.
Are 1 carat Princess Cut Lab Grown diamonds certified by IGI or GIA? +
Yes. 1 carat Princess Cut Lab Grown diamonds are commonly certified by IGI, GIA, and other
recognised laboratories. The grading report covers the 4Cs, proportions, polish, symmetry,
and growth method (CVD or HPHT).
Is a 1 carat Princess Cut diamond practical for everyday jewellery? +
Yes – as long as the corners are well protected. Princess Cuts have pointed corners that should
be secured with prongs or a protective setting. With proper setting and care, a 1 carat Princess
Cut is suitable for daily-wear rings, studs, and pendants.
Which ring settings look best with a 1 carat Princess Cut Lab Grown diamond? +
Princess Cuts look beautiful in solitaire, halo, channel-set, and three-stone designs. They pair
especially well with clean, contemporary settings that echo the square shape and sharp lines of
the diamond.
Does a 1 carat Princess Cut Lab Grown diamond offer good value compared to mined diamonds? +
Yes. Lab Grown diamonds are typically more affordable than mined diamonds, and Princess Cuts are
often priced lower per carat than Round stones. This combination provides excellent value while
maintaining a high level of brilliance and quality.
Are 1 carat Princess Cut Lab Grown diamonds only for rings, or also for pendants and earrings? +
Princess Cuts are very versatile. A 1 carat Princess Cut centre stone works beautifully in
engagement rings, but also in classic stud earrings, solitaire pendants, and geometric-inspired
fine jewellery designs.
