About this 1.02ct lab-grown heart diamond

This 1.02ct lab-grown heart sits in the classic one-carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG825657604 or 825657604. Listed at 8 retailers as of October 27, 2026, with prices from £182 to £1,645, a £1,462 spread on the same certified stone. Do Amore Diamonds lists it at £1,645. 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.
