About this 1.02ct lab-grown oval diamond

This 1.02ct lab-grown oval sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG781638098 or 781638098. Listed at 18 retailers as of October 29, 2026, with prices from $397 to $4,045, a $3,648 spread on the same certified stone. Brilliant Earth lists it at $4,045. 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.
