About this 0.86ct lab-grown heart diamond

This 0.86ct lab-grown heart sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840621550 or 840621550. Listed at 3 retailers as of November 4, 2026, with prices from €323 to €1,080, a €757 spread on the same certified stone. Taylor and Hart lists it at €1,080. 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.
