About this 1.02ct natural radiant diamond

This 1.02ct natural radiant sits in the classic one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2176274488. Listed at 12 retailers as of November 4, 2026, with prices from $3,364 to $5,176, a $1,812 spread on the same certified stone. Washington Diamond lists it at $5,176. 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.
