About this 4.64ct lab-grown heart diamond

This 4.64ct 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 LG832604735 or 832604735. Listed at 7 retailers as of October 31, 2026, with prices from €4,908 to €19,054, a €14,145 spread on the same certified stone. Taylor and Hart lists it at €19,054. 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.
