This 0.71ct lab-grown heart sits in the half to three-quarter carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG840632597 or 840632597. Listed at 4 retailers as of October 26, 2026, with prices from €340 to €686, a €346 spread on the same certified stone. Taylor and Hart lists it at €686. 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.
