About this 4.31ct lab-grown oval diamond

This 4.31ct lab-grown oval sits in the three to five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG581329749 or 581329749. Listed at 16 retailers as of October 30, 2026, with prices from £586 to £2,329, a £1,743 spread on the same certified stone. Brilliant Earth lists it at £2,329. 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.
