About this 11.35ct lab-grown oval diamond

This 11.35ct lab-grown oval sits in the over five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG617480239 or 617480239. Listed at 16 retailers as of October 29, 2026, with prices from £1,322 to £9,120, a £7,798 spread on the same certified stone. Brilliant Earth lists it at £9,120. 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.
