About this 5.1ct lab-grown marquise diamond

This 5.1ct lab-grown marquise sits in the over five carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG843607242 or 843607242. Listed at 20 retailers as of October 28, 2026, with a 667% 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.
