About this 0.46ct lab-grown round diamond

This 0.46ct lab-grown round sits in the sub-half-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG660420045 or 660420045. Listed at 14 retailers as of October 29, 2026, with prices from £56 to £517, a £461 spread on the same certified stone. MOH London lists it at £517. 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.
