This 0.91ct lab-grown heart sits in the just-under-one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG841633027 or 841633027. Listed at 7 retailers as of November 4, 2026, with prices from $437 to $1,510, a $1,073 spread on the same certified stone. MOH London lists it at $1,510. 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.
