About this 1.21ct natural radiant diamond

This 1.21ct natural radiant sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5212691065. Listed at 21 retailers as of November 4, 2026, with prices from $5,970 to $12,635, a $6,666 spread on the same certified stone. NZ Jewellers lists it at $12,635. 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.
