About this 1ct lab-grown heart diamond

This 1ct lab-grown heart sits in the classic one-carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included) and certified by IGI LG791634531 or 791634531. Listed at 10 retailers as of November 4, 2026, with prices from $288 to $992, a $704 spread on the same certified stone. MOH London lists it at $992. 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.
