About this 0.51ct lab-grown heart diamond

This 0.51ct lab-grown heart 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 LG770685287 or 770685287. Listed at 17 retailers as of October 30, 2026, with a 686% 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.
