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 LG677506064 or 677506064. Listed at 12 retailers as of October 30, 2026, with prices from $79 to $718, a $639 spread on the same certified stone. MOH London lists it at $718. 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.
