About this 0.51ct lab-grown marquise diamond

This 0.51ct lab-grown marquise sits in the half to three-quarter carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG532260853 or 532260853. Listed at 18 retailers as of November 4, 2026, with a 668% 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.
