About this 0.78ct lab-grown heart diamond

This 0.78ct lab-grown heart sits in the just-under-one-carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG840665084 or 840665084. Listed at 14 retailers as of October 27, 2026, with a 203% 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.
