About this 0.3ct lab-grown round diamond

This 0.3ct lab-grown round sits in the sub-half-carat band, graded I colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG459129278 or 459129278. Listed at 11 retailers as of October 29, 2026, with prices from £118 to £685, a £567 spread on the same certified stone. MOH London lists it at £685. 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.
