About this 1ct natural radiant diamond

This 1ct natural radiant sits in the classic one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1393469894. Listed at 19 retailers as of November 5, 2026, with prices from $2,348 to $6,213, a $3,866 spread on the same certified stone. NZ Jewellers lists it at $6,213. 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.
