This 1ct 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 6531627452. Listed at 7 retailers as of November 4, 2026, with prices from £695 to £1,071, a £376 spread on the same certified stone. Yorxs lists it at £1,071.
