About this 1.09ct lab-grown heart diamond

This 1.09ct lab-grown heart sits in the classic one-carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG818657606 or 818657606. Listed at 18 retailers as of October 30, 2026, with a 344% 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.
