About this 0.45ct lab-grown marquise diamond

This 0.45ct lab-grown marquise sits in the sub-half-carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG750535791 or 750535791. Listed at 15 retailers as of October 29, 2026, with a 431% 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.
