About this 0.42ct lab-grown heart diamond

This 0.42ct lab-grown heart sits in the sub-half-carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG669469717 or 669469717. Listed at 11 retailers as of October 29, 2026, with prices from $79 to $721, a $642 spread on the same certified stone. MOH London lists it at $721. 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.
