About this 0.42ct lab-grown heart diamond

This 0.42ct lab-grown heart sits in the sub-half-carat band, graded D colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG710561143 or 710561143. Listed at 14 retailers as of October 29, 2026, with a 297% 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.
