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 6425656978. Listed at 25 retailers as of October 29, 2026, with prices from $16,776 to $30,101, a $13,325 spread on the same certified stone. MOH London lists it at $30,101. 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.
