This 0.5ct natural radiant sits in the half to three-quarter carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 831667984. Listed at 16 retailers as of November 4, 2026, with prices from $893 to $3,068, a $2,176 spread on the same certified stone. NZ Jewellers lists it at $3,068. 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.
