Marquise Cut Internally Flawless Lab Grown Diamonds

IF is premium clarity that exceeds the marquise's visual needs. The brilliant faceting conceals inclusions at lower grades. IF costs less than Flawless and looks identical. For on-finger beauty, VS1 or VS2 delivers the same result. IF is most valuable for the grading report, heirloom purposes, or very large marquise diamonds (3+ carats).

Both are eye-clean with no visible difference. VS1 costs 15% to 25% less. In the marquise, those savings are best invested in finding a stone with aligned tips, matching curves, and minimal bowtie, which impact the marquise's dramatic beauty far more than the IF-to-VS1 clarity step.

IF is worth it if the report matters, for very large marquise diamonds, or for personal satisfaction. For most marquise buyers, the shape's beauty depends on tip alignment, curve symmetry, and bowtie quality. These cut factors should drive your budget allocation before clarity upgrades.

Internally Flawless clarity is always eye-clean. No inclusions visible under 10x magnification, only minor surface blemishes. The marquise cut's brilliant-cut faceting helps mask minor inclusions.
