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), with a very-good cut grade and certified by IGI LG830619537 or 830619537. Listed at 5 retailers as of November 5, 2026, with prices from $392 to $2,032, a $1,640 spread on the same certified stone. MOH London lists it at $2,032. 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.
