About this 0.51ct lab-grown emerald diamond

This 0.51ct lab-grown emerald sits in the half to three-quarter carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG837660506 or 837660506. Listed at 19 retailers as of October 29, 2026, with a 650% 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.
