About this 1.2ct natural princess diamond

This 1.2ct natural princess sits in the classic one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 2456418545. Listed at 15 retailers as of November 2, 2026, with prices from $2,446 to $8,003, a $5,557 spread on the same certified stone. NZ Jewellers lists it at $8,003. 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.
