About this 1.22ct lab-grown heart diamond

This 1.22ct lab-grown heart sits in the classic one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG681597493 or 681597493. Listed at 18 retailers as of October 29, 2026, with prices from £162 to £1,560, a £1,398 spread on the same certified stone. Do Amore Diamonds lists it at £1,560. 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.
