About this 5.03ct lab-grown marquise diamond

This 5.03ct lab-grown marquise sits in the over five carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG831609325 or 831609325. Listed at 21 retailers as of October 27, 2026, with a 337% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
