This 1.56ct 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 LG834612610 or 834612610. Listed at 8 retailers as of October 29, 2026, with prices from $216 to $1,124, a $908 spread on the same certified stone. MOH London lists it at $1,124. 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.
