About this 1.15ct lab-grown heart diamond

This 1.15ct lab-grown heart sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG582385678 or 582385678. Listed at 20 retailers as of October 30, 2026, with prices from $399 to $2,263, a $1,864 spread on the same certified stone. Brilliant Earth lists it at $2,263. 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.
