This 3.05ct 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 LG519244561 or 519244561. Listed at 17 retailers as of November 6, 2026, with prices from £317 to £3,310, a £2,993 spread on the same certified stone. Brilliant Earth lists it at £3,310. 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.
