About this 0.42ct natural radiant diamond

This 0.42ct natural radiant sits in the sub-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 5181390981. Listed at 4 retailers as of October 29, 2026, with prices from $1,328 to $2,015, a $687 spread on the same certified stone. MOH London lists it at $2,015. 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.
