About this 5.05ct lab-grown marquise diamond

This 5.05ct lab-grown marquise sits in the over five carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included) and certified by IGI LG791628794 or 791628794. Listed at 28 retailers as of October 30, 2026, with a 441% 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.
