About this 5ct lab-grown marquise diamond

This 5ct lab-grown marquise sits in the over five carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG842609449 or 842609449. Listed at 19 retailers as of November 1, 2026, with prices from £437 to £2,586, a £2,149 spread on the same certified stone. Rare Carat lists it at £2,586. 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.
