About this 1.8ct natural radiant diamond

This 1.8ct natural radiant sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2225731941. Listed at 16 retailers as of October 28, 2026, with prices from $21,443 to $36,862, a $15,419 spread on the same certified stone. MOH London lists it at $36,862. 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.
