About this 1.21ct natural marquise diamond

This 1.21ct natural marquise sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 6207861774. Listed at a single retailer as of October 29, 2026. If it later appears at another store, Carat Hunter will surface the price comparison automatically. 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.
