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 LG843608351 or 843608351. Listed at 6 retailers as of November 1, 2026, with prices from $667 to $1,572, a $906 spread on the same certified stone. MOH London lists it at $1,572. 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.
