About this 1.56ct natural radiant diamond

This 1.56ct natural radiant sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA. Listed at 11 retailers as of November 4, 2026, with prices from $5,870 to $12,282, a $6,412 spread on the same certified stone. NZ Jewellers lists it at $12,282. 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.
