About this 0.75ct natural marquise diamond

This 0.75ct natural marquise sits in the just-under-one-carat band, graded J 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 5111426019. Listed at 3 retailers as of November 2, 2026, with a relatively tight 15% 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.
