About this 3.45ct lab-grown princess diamond

This 3.45ct lab-grown princess sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG768632820 or 768632820. Listed at 18 retailers as of October 30, 2026, with a 588% 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.
