About this 0.81ct natural radiant diamond

This 0.81ct natural radiant sits in the just-under-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 2131565100. Listed at 5 retailers as of November 2, 2026, with prices from £604 to £1,309, a £706 spread on the same certified stone. MOH London lists it at £1,309. 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.
