This 0.71ct lab-grown heart sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG836612972 or 836612972. Listed at 17 retailers as of October 30, 2026, with prices from £169 to £953, a £785 spread on the same certified stone. Reve Diamonds lists it at £953. 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.
