About this 0.38ct lab-grown round diamond

This 0.38ct lab-grown round sits in the sub-half-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG462172849 or 462172849. Listed at 9 retailers as of October 29, 2026, with prices from £132 to £771, a £638 spread on the same certified stone. MOH London lists it at £771. 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.
