About this 3.09ct lab-grown heart diamond

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 12 retailers as of October 31, 2026, with prices from $1,624 to $5,922, a $4,298 spread on the same certified stone. Taylor and Hart lists it at $5,922. 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.
