About this 4.3ct natural marquise diamond

This 4.3ct natural marquise sits in the three to five carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 5221919332. Listed at 2 retailers as of October 31, 2026, with a relatively tight 1% spread, which is unusual at this carat range and suggests competitive pricing across the listings. SI-grade stones are eye-clean roughly 60 to 70% of the time at this carat range. Check the inclusion plot on the cert and ask the retailer for high-resolution video before buying.
