This 3.09ct lab-grown oval sits in the three to five carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG519247680 or 519247680. Listed at 16 retailers as of October 29, 2026, with prices from £403 to £2,100, a £1,697 spread on the same certified stone. MOH London lists it at £2,100. 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.
