About this 1.31ct natural radiant diamond

This 1.31ct natural radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 11992451. Listed at 7 retailers as of October 29, 2026, with prices from $8,779 to $15,999, a $7,220 spread on the same certified stone. MOH London lists it at $15,999. 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.
