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 LG836612966 or 836612966. Listed at 17 retailers as of November 1, 2026, with prices from £262 to £1,266, a £1,005 spread on the same certified stone. MOH London lists it at £1,266. 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.
