About this 3.05ct lab-grown marquise diamond

This 3.05ct lab-grown marquise sits in the three to five carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG840654414 or 840654414. Listed at 5 retailers as of November 3, 2026, with prices from £313 to £2,070, a £1,757 spread on the same certified stone. Frank Darling lists it at £2,070. 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.
