This 0.51ct lab-grown heart sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG836610913 or 836610913. Listed at 17 retailers as of November 4, 2026, with prices from $301 to $1,633, a $1,332 spread on the same certified stone. Reve Diamonds lists it at $1,633. 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.
