About this 3.03ct lab-grown marquise diamond

This 3.03ct lab-grown marquise sits in the three to five carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG843676100 or 843676100. Listed at 6 retailers as of October 28, 2026, with a 433% 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.
