About this 2.5ct lab-grown marquise diamond

This 2.5ct lab-grown marquise sits in the two to three carat band, graded G colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG842655798 or 842655798. Listed at 3 retailers as of November 1, 2026, with prices from £265 to £2,165, a £1,899 spread on the same certified stone. Rare Carat lists it at £2,165. 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.
