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 very-good cut grade and certified by IGI LG530203619 or 530203619. Listed at 4 retailers as of October 26, 2026, with prices from $640 to $1,500, a $861 spread on the same certified stone. MOH London lists it at $1,500. 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.
