About this 0.51ct lab-grown pear diamond

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 LG407941393 or 407941393. Listed at 11 retailers as of October 29, 2026, with prices from £204 to £1,021, a £817 spread on the same certified stone. MOH London lists it at £1,021. 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.
