This 1.51ct lab-grown pear sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG557240421 or 557240421. Listed at 6 retailers as of November 1, 2026, with prices from $638 to $1,484, a $847 spread on the same certified stone. MOH London lists it at $1,484. 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.
