This 3.02ct lab-grown oval sits in the three to five carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG831679691 or 831679691. Listed at 3 retailers as of November 6, 2026, with prices from £279 to £1,681, a £1,402 spread on the same certified stone. Brilliant Earth lists it at £1,681. 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.
