About this 1.2ct natural radiant diamond

This 1.2ct natural radiant sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3525071502. Listed at 8 retailers as of November 2, 2026, with prices from $5,510 to $9,843, a $4,333 spread on the same certified stone. NZ Jewellers lists it at $9,843. 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.
