About this 1.91ct lab-grown oval diamond

This 1.91ct lab-grown oval sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG522252576 or 522252576. Listed at 3 retailers as of October 28, 2026, with prices from $819 to $1,280, a $461 spread on the same certified stone. Rare Carat lists it at $1,280. 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.
