About this 1.37ct lab-grown heart diamond

This 1.37ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LGG1202218 or G1202218. Listed at 2 retailers as of November 1, 2026, with prices from $614 to $1,426, a $812 spread on the same certified stone. MOH London lists it at $1,426. 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.
