About this 1.2ct natural radiant diamond

This 1.2ct natural radiant sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1558958102. Listed at 13 retailers as of November 5, 2026, with prices from $3,144 to $8,821, a $5,677 spread on the same certified stone. NZ Jewellers lists it at $8,821. 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.
