About this 0.5ct natural radiant diamond

This 0.5ct natural radiant sits in the half to three-quarter carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2477456492. Listed at 15 retailers as of October 30, 2026, with prices from $326 to $1,354, a $1,028 spread on the same certified stone. NZ Jewellers lists it at $1,354. 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.
