This 3ct lab-grown marquise sits in the three to five carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG840651037 or 840651037. Listed at 8 retailers as of October 29, 2026, with prices from £1,070 to £3,277, a £2,207 spread on the same certified stone. Do Amore Diamonds lists it at £3,277. 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.
