About this 1.8ct natural radiant diamond

This 1.8ct natural radiant sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2186042049. Listed at 12 retailers as of November 1, 2026, with prices from $19,799 to $30,472, a $10,672 spread on the same certified stone. MOH London lists it at $30,472. 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.
