About this 1.51ct lab-grown heart diamond

This 1.51ct lab-grown heart sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG818679709 or 818679709. Listed at 5 retailers as of November 1, 2026, with prices from $678 to $1,603, a $925 spread on the same certified stone. MOH London lists it at $1,603. 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.
