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 very-good cut grade and certified by IGI LG849675891 or 849675891. Listed at 6 retailers as of November 4, 2026, with prices from $546 to $1,995, a $1,449 spread on the same certified stone. MOH London lists it at $1,995. 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.
