This 0.5ct lab-grown heart sits in the half to three-quarter carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG831688997 or 831688997. Listed at 4 retailers as of November 4, 2026, with prices from $284 to $1,093, a $809 spread on the same certified stone. Taylor and Hart lists it at $1,093. 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.
