This 2.5ct lab-grown marquise sits in the two to three carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG841661265 or 841661265. Listed at 14 retailers as of November 1, 2026, with prices from £353 to £1,900, a £1,547 spread on the same certified stone. Brilliant Earth lists it at £1,900. 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.
