About this 1.2ct lab-grown heart diamond

This 1.2ct lab-grown heart sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG837622437 or 837622437. Listed at 15 retailers as of November 4, 2026, with prices from $298 to $1,346, a $1,049 spread on the same certified stone. MOH London lists it at $1,346. 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.
