This 1.86ct lab-grown heart sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LGG1210807 or G1210807. Listed at 2 retailers as of November 1, 2026, with prices from $660 to $1,534, a $874 spread on the same certified stone. MOH London lists it at $1,534. 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.
