About this 1.21ct natural radiant diamond

This 1.21ct natural radiant sits in the classic one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1527349081. Listed at 6 retailers as of November 2, 2026, with prices from $4,322 to $9,140, a $4,818 spread on the same certified stone. NZ Jewellers lists it at $9,140. 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.
