Price Comparison — Round Brilliant 1 Carat
Save 75–92% vs the natural equivalent. Same optical and chemical properties — different origin.
Round brilliants are the most light-efficient cut ever engineered. The 57–58 facets are mathematically optimized for fire and scintillation — which is why rounds cost a slight premium over other shapes. If you're choosing between an Excellent and a Very Good cut, go Excellent: the difference is visible under any light.
One carat is the most searched diamond weight globally — it hits a psychological threshold where the stone is unambiguously significant. A 1ct lab-grown at StudsDirect runs $580–$980 depending on shape, cut, and clarity — versus $4,500–$7,000 for an equivalent natural diamond at retail.
A 1ct round brilliant is approximately 6.5mm diameter — clearly present in all settings, photographs beautifully, and reads as the classic engagement ring weight.
Rounds are forgiving on color — G or H faces up white in most settings. If you're setting in yellow gold, H–I is indistinguishable from D–F and saves real money.
VS2 is the sweet spot for rounds. Inclusions are masked by the facet pattern. Eye-clean VS2 beats SI1 with a visible inclusion every time.
Classic prong (4 or 6-prong solitaire) maximizes light entry. Bezel settings protect the stone well for active hands but slightly reduce brilliance at the edges.
The 1ct size works on all hand sizes. On smaller hands (size 4–5), it reads as a statement piece. On larger hands, it reads as refined.
"Every round diamond we carry goes through the same QC process I applied when grading for export clients at SEEPZ. The cut grade isn't a box to check — it's the difference between a stone that looks alive and one that sits flat. For the 1 Carat round, I look specifically at the table percentage and crown angle. We don't carry stones that don't meet that standard."
