Marquise Cut SI1 Lab Grown Diamonds

Yes, many marquise SI1 lab grown diamonds are eye-clean. The brilliant faceting is effective at masking inclusions. Look for SI1 marquise diamonds where inclusions are positioned away from the bowtie area and both tips. Off-center inclusions along the curves give the best chance at an eye-clean SI1 marquise.

Check three things: bowtie severity (minimal), inclusion position (away from center and both tips), and symmetry (aligned tips, matching curves). The bowtie area draws the eye, so inclusions there are most visible. Tip inclusions can also create durability concerns. Curve-area inclusions are least noticeable.

SI1 saves 15% to 25% over VS2. If you find an eye-clean SI1 with good symmetry and minimal bowtie, the on-finger result is identical to VS2. The savings can fund a larger stone. The marquise's biggest-face-up-per-carat advantage combined with SI1 savings creates maximum visual size per dollar.

SI1 clarity is in many brilliant cuts eye-clean in marquise cut diamonds. Inclusions noticeable under 10x magnification, sometimes visible to the naked eye depending on the cut. The marquise cut's brilliant-cut faceting helps mask minor inclusions.
