About this 1.03ct lab-grown heart diamond

This 1.03ct 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 LG836618807 or 836618807. Listed at 16 retailers as of October 30, 2026, with prices from $289 to $1,892, a $1,603 spread on the same certified stone. Brilliant Earth lists it at $1,892. 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.
