About this 1.55ct lab-grown heart diamond

This 1.55ct lab-grown heart sits in the one-and-a-half to two carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG830640123 or 830640123. Listed at 19 retailers as of November 4, 2026, with a 405% 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.
