About this 3.02ct lab-grown marquise diamond

This 3.02ct lab-grown marquise sits in the three to five carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG800675802 or 800675802. Listed at 25 retailers as of October 31, 2026, with a 689% 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.
