About this 0.5ct natural radiant diamond

This 0.5ct natural radiant sits in the half to three-quarter carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7428519737. Listed at 18 retailers as of October 30, 2026, with prices from $1,067 to $3,997, a $2,930 spread on the same certified stone. NZ Jewellers lists it at $3,997. 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.
