About this 1.02ct lab-grown heart diamond

This 1.02ct lab-grown heart sits in the classic one-carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG825656376 or 825656376. Listed at 19 retailers as of October 30, 2026, with a 333% 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.
