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 VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1226339346. Listed at 4 retailers as of November 4, 2026, with prices from £2,637 to £4,252, a £1,614 spread on the same certified stone. MOH London lists it at £4,252. 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.
