About this 0.4ct lab-grown heart diamond

This 0.4ct lab-grown heart sits in the sub-half-carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG847619159 or 847619159. Listed at 7 retailers as of October 26, 2026, with a 184% 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.
