About this 3ct lab-grown marquise diamond

This 3ct lab-grown marquise sits in the three to five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG835636839 or 835636839. Listed at 6 retailers as of November 4, 2026, with prices from £317 to £2,076, a £1,759 spread on the same certified stone. Frank Darling lists it at £2,076. 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.
