About this 0.71ct lab-grown heart diamond

This 0.71ct lab-grown heart sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG825667285 or 825667285. Listed at 17 retailers as of November 1, 2026, with prices from £246 to £1,117, a £871 spread on the same certified stone. Reve Diamonds lists it at £1,117. 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.
