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 IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG698502216 or 698502216. Listed at 21 retailers as of October 28, 2026, with prices from $400 to $3,320, a $2,920 spread on the same certified stone. Rare Carat lists it at $3,320. 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.
