About this 1.8ct lab-grown oval diamond

This 1.8ct lab-grown oval sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LG516238513 or 516238513. Listed at 11 retailers as of October 28, 2026, with prices from $501 to $1,564, a $1,063 spread on the same certified stone. Rare Carat lists it at $1,564. 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.
