About this 0.51ct lab-grown heart diamond

This 0.51ct lab-grown heart 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 LG839611359 or 839611359. Listed at 16 retailers as of October 25, 2026, with a 243% 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.
