This 1.51ct lab-grown heart sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG844636610 or 844636610. Listed at 6 retailers as of November 1, 2026, with prices from $668 to $1,573, a $905 spread on the same certified stone. MOH London lists it at $1,573. 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.
