Price Comparison — Marquise Cut 1 Carat
Save 75–92% vs the natural equivalent. Same optical and chemical properties — different origin.
Marquise cuts deliver the most finger surface coverage per carat of any shape — a 1ct marquise looks larger face-up than a 1ct round. The elongated boat shape with pointed tips creates a dramatic silhouette that photographs beautifully. The shape dates to the 18th century French court.
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.
Both pointed tips concentrate color. F or G color minimum for white-metal settings — the tips are the most color-prominent areas and will show warmth in H and below.
VS2 floor. Both tips are structurally thin — avoid inclusions in the tips entirely. Center inclusions are better masked by the brilliant faceting.
V-tip prongs are mandatory — the sharp points chip without protection. Classic prong count is 6 (2 tips + 4 sides). East-west orientation is a bold contemporary look. Traditional north-south maximizes the elongating effect.
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 marquise 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 marquise, I look specifically at the bow-tie severity and tip definition. We don't carry stones that don't meet that standard."
