About this 1.21ct natural princess diamond

This 1.21ct natural princess sits in the classic one-carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 1236961321. Listed at 10 retailers as of November 1, 2026, with a 118% 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.
