This 0.51ct lab-grown pear sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG407915389 or 407915389. Listed at 11 retailers as of November 1, 2026, with prices from $391 to $1,946, a $1,555 spread on the same certified stone. MOH London lists it at $1,946. 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.
