About this 0.9ct natural marquise diamond

This 0.9ct natural marquise sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 7558581586. Listed at 15 retailers as of October 29, 2026, with a 81% 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.
