This 3.07ct lab-grown heart sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG836621955 or 836621955. Listed at 21 retailers as of November 2, 2026, with prices from $1,990 to $12,314, a $10,324 spread on the same certified stone. Brilliant Earth lists it at $12,314. 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.
