About this 1.21ct natural radiant diamond

This 1.21ct natural radiant sits in the classic one-carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2223604198. Listed at 10 retailers as of November 5, 2026, with prices from £1,538 to £3,609, a £2,072 spread on the same certified stone. NZ Jewellers lists it at £3,609. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
