About this 1.58ct natural radiant diamond

This 1.58ct natural radiant sits in the one-and-a-half to two carat band, graded L colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA. Listed at 3 retailers as of November 4, 2026, with prices from $4,492 to $5,507, a $1,016 spread on the same certified stone. The Perfect Carat lists it at $5,507. 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.
