About this 3ct lab-grown marquise diamond

This 3ct lab-grown marquise sits in the three to five carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG840613163 or 840613163. Listed at 13 retailers as of October 30, 2026, with a 459% 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.
