Frequently Asked Questions
What makes cushion cut lab grown diamonds unique? +
Cushion cut diamonds combine soft, rounded edges with brilliant faceting, creating a
romantic, vintage look. Their pillow-like shape offers excellent fire and a warm, elegant
sparkle that many people love for engagement rings.
Do cushion cut diamonds look larger or smaller than round diamonds of the same carat weight? +
Cushion cuts tend to appear slightly smaller than round and oval diamonds due to their
deeper cut. However, their soft, open face-up shape gives them a bold, luxurious presence
that stands out beautifully in jewellery.
What is the difference between cushion brilliant and cushion modified cuts? +
Cushion brilliant diamonds have larger, more defined facets and deliver crisp, intense
sparkle. Cushion modified diamonds feature extra facets and create a “crushed ice” look
with softer, shimmering reflections. Both styles are popular and beautiful.
What is the ideal length-to-width ratio for cushion cut diamonds? +
Ratios between 1.00 and 1.05 give a perfect square shape, while 1.10–1.20 create
a more elongated rectangular appearance. Each ratio offers a distinct style, depending on
personal preference.
Do cushion cut diamonds hide inclusions well? +
Yes. Cushion cuts hide inclusions effectively due to their deeper cut and brilliant
faceting. Most buyers choose VVS–VS clarity for a clean appearance, especially in lab grown diamonds.
Are cushion cut diamonds good for engagement rings and daily wear? +
Absolutely. Their rounded corners make them less prone to chipping compared to shapes
with sharp points. They are durable, timeless, and versatile in many engagement ring
settings.
Which settings best complement cushion cut diamonds? +
Cushion cuts look stunning in halo, solitaire, vintage-inspired, double-halo, pavé, and
3-stone settings. Their shape blends beautifully with both classic and contemporary designs.
Are cushion cut lab grown diamonds certified by IGI or GIA? +
Yes. Cushion cut lab grown diamonds are certified by IGI, GIA, and other trusted gemological
laboratories, ensuring accurate grading of the 4Cs and growth method.
What diamond colors look best in cushion cut shapes? +
Cushion diamonds hold color slightly more than round diamonds. For a bright, white look,
many buyers prefer D–H color. Lab grown diamonds make high color grades more affordable.
Do cushion cut lab grown diamonds come in different sizes and styles? +
Yes. Cushion cuts are available from under 0.50 ct to 10+ ct in both brilliant and modified
styles, offering excellent variety for engagement rings, studs, and fine jewellery.
