About this 6.03ct lab-grown oval diamond

This 6.03ct lab-grown oval sits in the over five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG819645020 or 819645020. Listed at 13 retailers as of October 30, 2026, with prices from £678 to £3,254, a £2,576 spread on the same certified stone. Brilliant Earth lists it at £3,254. 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.
