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 LG848666876 or 848666876. Listed at 7 retailers as of November 3, 2026, with prices from £528 to £1,287, a £759 spread on the same certified stone. MOH London lists it at £1,287. 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.
