About this 4.08ct lab-grown marquise diamond

This 4.08ct lab-grown marquise sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG784694921 or 784694921. Listed at 22 retailers as of October 26, 2026, with a 87% 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.
