About this 1ct lab-grown oval diamond

This 1ct lab-grown oval sits in the classic one-carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840619124 or 840619124. Listed at 13 retailers as of October 30, 2026, with prices from $325 to $2,975, a $2,651 spread on the same certified stone. Brilliant Earth lists it at $2,975. 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.
