About this 4.51ct lab-grown oval diamond

This 4.51ct lab-grown oval sits in the three to five carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG660491787 or 660491787. Listed at 8 retailers as of October 29, 2026, with prices from £524 to £2,399, a £1,875 spread on the same certified stone. MOH London lists it at £2,399. 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.
