About this 0.78ct lab-grown heart diamond

This 0.78ct lab-grown heart sits in the just-under-one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG774602253 or 774602253. Listed at 8 retailers as of October 29, 2026, with prices from $298 to $1,124, a $826 spread on the same certified stone. MOH London lists it at $1,124. 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.
