About this 0.34ct lab-grown round diamond

This 0.34ct 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 LG462172762 or 462172762. Listed at 10 retailers as of October 26, 2026, with prices from £121 to £700, a £579 spread on the same certified stone. MOH London lists it at £700. 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.
