About this 0.57ct natural radiant diamond

This 0.57ct natural radiant sits in the half to three-quarter carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6542330290. Listed at 15 retailers as of November 5, 2026, with prices from £287 to £1,304, a £1,018 spread on the same certified stone. NZ Jewellers lists it at £1,304. 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.
