This 0.42ct lab-grown heart sits in the sub-half-carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG844684523 or 844684523. Listed at 9 retailers as of October 26, 2026, with prices from $141 to $893, a $752 spread on the same certified stone. MOH London lists it at $893. 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.
