About this 0.51ct lab-grown marquise diamond

This 0.51ct 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 LG825667283 or 825667283. Listed at 19 retailers as of October 28, 2026, with a 573% 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.
