About this 0.5ct lab-grown round diamond

This 0.5ct lab-grown round sits in the half to three-quarter carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG506193156 or 506193156. Listed at 13 retailers as of October 31, 2026, with prices from £239 to £1,247, a £1,009 spread on the same certified stone. MOH London lists it at £1,247. 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.
