About this 0.78ct lab-grown heart diamond

This 0.78ct lab-grown heart sits in the just-under-one-carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG774621417 or 774621417. Listed at 8 retailers as of October 25, 2026, with prices from €266 to €990, a €724 spread on the same certified stone. MOH London lists it at €990. 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.
