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 IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG743523320 or 743523320. Listed at 7 retailers as of October 29, 2026, with prices from $380 to $1,137, a $757 spread on the same certified stone. MOH London lists it at $1,137. 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.
