Frequently Asked Questions
Why is the round cut the most popular diamond shape? +
The round brilliant cut is the most popular because it offers maximum brilliance, fire,
and light performance. Its 57/58 precision-cut facets are engineered to reflect the highest
amount of light, making it the sparkliest of all diamond shapes.
Do round cut lab grown diamonds sparkle more than other shapes? +
Yes. Round brilliants are specifically designed to maximize light return, giving them
superior sparkle compared to most fancy shapes. Their symmetrical design enhances brilliance,
fire, and scintillation from every angle.
Are round cut lab grown diamonds more expensive than other shapes? +
Round cut diamonds typically cost slightly more because they require more rough diamond
material to achieve perfect proportions. However, lab grown diamonds allow buyers to get
larger, higher-quality round stones at far more accessible prices than mined diamonds.
What makes a round cut diamond “ideal” or “excellent” cut? +
An ideal or excellent cut round diamond has perfect symmetry, balanced proportions,
and optimal facet alignment. These factors maximize brilliance and ensure that the
diamond reflects light with extraordinary intensity.
What settings look best with round cut lab grown diamonds? +
Round diamonds are the most versatile and work beautifully in solitaire, halo, pavé,
3-stone, and vintage settings. They also pair perfectly with plain, diamond, or hidden-halo
bands, making them a timeless choice for engagement rings.
Are round cut lab grown diamonds good for everyday wear? +
Absolutely. Their symmetrical round shape and lack of sharp corners make them durable,
secure, and ideal for rings worn daily. They resist chipping better than fancy shapes
like pear, marquise, or princess.
Do round cut diamonds look larger than other shapes of the same carat? +
Round diamonds may appear slightly smaller compared to elongated shapes like oval or emerald,
but they offer unmatched brilliance and light return, which makes them visually stand out
even at smaller sizes.
Are round cut lab grown diamonds certified by IGI or GIA? +
Yes. Round cut lab grown diamonds are graded by the same reputable laboratories—IGI, GIA,
and others. Each certificate includes details on cut grade, symmetry, polish, color,
clarity, and carat weight.
What colors and clarities are recommended for round diamonds? +
Round diamonds are excellent at masking inclusions and color because of their intense sparkle.
Most buyers choose D–I color and VVS–VS clarity for the best balance of beauty and value,
especially in lab grown diamonds.
Do round cut lab grown diamonds come in different sizes? +
Yes. They are available from under 0.50 carat all the way to 10+ carats, with a wide range
of cut grades, colors, and clarities. Their consistent proportions make them the most
universally loved diamond shape.
