About this 1.4ct lab-grown oval diamond

This 1.4ct lab-grown oval sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840634492 or 840634492. Listed at 11 retailers as of October 28, 2026, with prices from $429 to $4,292, a $3,864 spread on the same certified stone. Rare Carat lists it at $4,292. 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.
