About this 1.3ct natural marquise diamond

This 1.3ct natural marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded H 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 1558695560. Listed at 6 retailers as of November 1, 2026, with a 71% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
