About this 1.08ct lab-grown heart diamond

This 1.08ct lab-grown heart sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG836612941 or 836612941. Listed at 20 retailers as of October 30, 2026, with prices from £190 to £1,134, a £945 spread on the same certified stone. Brilliant Earth lists it at £1,134. 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.
