This 1.51ct 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 LG838601057 or 838601057. Listed at 7 retailers as of November 2, 2026, with prices from $442 to $1,194, a $752 spread on the same certified stone. MOH London lists it at $1,194. 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.
