About this 0.3ct lab-grown round diamond

This 0.3ct lab-grown round sits in the sub-half-carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG544242209 or 544242209. Listed at 12 retailers as of October 29, 2026, with prices from £64 to £583, a £519 spread on the same certified stone. MOH London lists it at £583. 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.
