About this 1.18ct lab-grown heart diamond

This 1.18ct lab-grown heart sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG607350823 or 607350823. Listed at 9 retailers as of November 4, 2026, with prices from $327 to $1,315, a $987 spread on the same certified stone. MOH London lists it at $1,315. 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.
