About this 3.47ct lab-grown heart diamond

This 3.47ct lab-grown heart sits in the three to five carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG728549346 or 728549346. Listed at 20 retailers as of October 31, 2026, with a 349% 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.
