About this 1.21ct lab-grown heart diamond

This 1.21ct lab-grown heart sits in the classic one-carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG678596550 or 678596550. Listed at 11 retailers as of October 29, 2026, with prices from $394 to $1,365, a $972 spread on the same certified stone. MOH London lists it at $1,365. 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.
