About this 3ct lab-grown heart diamond

This 3ct lab-grown heart sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG768631954 or 768631954. Listed at 14 retailers as of November 1, 2026, with prices from £1,048 to £11,729, a £10,681 spread on the same certified stone. Novita Diamonds lists it at £11,729. 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.
