About this 0.78ct lab-grown heart diamond

This 0.78ct lab-grown heart sits in the just-under-one-carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included) and certified by IGI LG788666496 or 788666496. Listed at 8 retailers as of November 1, 2026, with prices from $361 to $1,139, a $778 spread on the same certified stone. MOH London lists it at $1,139. 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.
