This 0.31ct lab-grown heart sits in the sub-half-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG847661673 or 847661673. Listed at 6 retailers as of October 27, 2026, with prices from $102 to $344, a $242 spread on the same certified stone. Taylor and Hart lists it at $344. 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.
