About this 1.64ct lab-grown oval diamond

This 1.64ct lab-grown oval sits in the one-and-a-half to two carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG818653701 or 818653701. Listed at 9 retailers as of October 28, 2026, with prices from $777 to $6,088, a $5,311 spread on the same certified stone. Brilliant Earth lists it at $6,088. 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.
