This 0.31ct lab-grown heart sits in the sub-half-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG847661827 or 847661827. Listed at 7 retailers as of November 4, 2026, with prices from $184 to $1,180, a $996 spread on the same certified stone. MOH London lists it at $1,180. 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.
