About this 1.28ct lab-grown marquise diamond

This 1.28ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG846692024 or 846692024. Listed at 15 retailers as of October 27, 2026, with a 85% 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.
