About this 0.51ct lab-grown marquise diamond

This 0.51ct lab-grown marquise sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG804628744 or 804628744. Listed at 9 retailers as of October 31, 2026, with a 103% 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.
