This 3.01ct lab-grown marquise sits in the three to five carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG849652531 or 849652531. Listed at 8 retailers as of October 30, 2026, with prices from £372 to £1,954, a £1,582 spread on the same certified stone. Brilliant Earth lists it at £1,954. 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.
