About this 3.18ct lab-grown heart diamond

This 3.18ct lab-grown heart sits in the three to five carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6532323029. Listed at 12 retailers as of October 31, 2026, with a 331% 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.
