About this 1.25ct natural radiant diamond

This 1.25ct natural radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7386505741. Listed at 16 retailers as of November 5, 2026, with prices from £2,344 to £5,078, a £2,734 spread on the same certified stone. NZ Jewellers lists it at £5,078. 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.
