About this 10.78ct lab-grown princess diamond

This 10.78ct lab-grown princess sits in the over five carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG723523473 or 723523473. Listed at 16 retailers as of October 29, 2026, with a 240% 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.
