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 6203890649. Listed at 24 retailers as of October 30, 2026, with prices from $13,935 to $26,119, a $12,184 spread on the same certified stone. NZ Jewellers lists it at $26,119. 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.
