About this 0.64ct lab-grown marquise diamond

This 0.64ct lab-grown marquise sits in the half to three-quarter carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG678546535 or 678546535. Listed at 24 retailers as of October 26, 2026, with a 541% 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.
