This 0.51ct 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 LG839630301 or 839630301. Listed at 15 retailers as of November 4, 2026, with prices from $264 to $1,826, a $1,562 spread on the same certified stone. Reve Diamonds lists it at $1,826. 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.
