This 3.09ct 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 LG847656426 or 847656426. Listed at 17 retailers as of November 2, 2026, with prices from $2,076 to $8,480, a $6,404 spread on the same certified stone. Taylor and Hart lists it at $8,480. 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.
