About this 1.35ct lab-grown radiant diamond

This 1.35ct lab-grown 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 and certified by IGI LG564354983 or 564354983. Listed at 21 retailers as of October 27, 2026, with prices from $392 to $4,259, a $3,867 spread on the same certified stone. Queensmith lists it at $4,259. 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.
