This 3.03ct lab-grown oval sits in the three to five carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG849675946 or 849675946. Listed at 7 retailers as of October 31, 2026, with prices from £541 to £1,375, a £834 spread on the same certified stone. Rare Carat lists it at £1,375. 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.
