This 1.29ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LGG1201805. Listed at 6 retailers as of October 31, 2026, with prices from $377 to $1,725, a $1,348 spread on the same certified stone. Taylor and Hart lists it at $1,725. 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.
