This 0.5ct 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 LG836612983 or 836612983. Listed at 15 retailers as of October 30, 2026, with prices from $190 to $1,162, a $972 spread on the same certified stone. Reve Diamonds lists it at $1,162. 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.
