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 LG436044197 or 436044197. Listed at 11 retailers as of November 1, 2026, with prices from £204 to £1,018, a £813 spread on the same certified stone. MOH London lists it at £1,018. 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.
