About this 1ct natural radiant diamond

This 1ct natural radiant sits in the classic one-carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2556721766. Listed at 21 retailers as of November 3, 2026, with prices from $4,473 to $10,194, a $5,721 spread on the same certified stone. NZ Jewellers lists it at $10,194. 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.
