This 1.54ct lab-grown oval sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG524240472 or 524240472. Listed at 6 retailers as of November 1, 2026, with prices from $648 to $1,513, a $866 spread on the same certified stone. MOH London lists it at $1,513. 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.
