About this 0.5ct lab-grown radiant diamond

This 0.5ct lab-grown radiant sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG744510351 or 744510351. Listed at 12 retailers as of October 29, 2026, with prices from $367 to $2,026, a $1,658 spread on the same certified stone. MOH London lists it at $2,026. 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.
