This 1.71ct lab-grown heart sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VVS1 clarity (very-very-slightly-included) and certified by IGI LGG1201814 or G1201814. Listed at 2 retailers as of November 1, 2026, with prices from $1,083 to $2,517, a $1,434 spread on the same certified stone. MOH London lists it at $2,517. 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.
