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 LG786691180 or 786691180. Listed at 20 retailers as of October 30, 2026, with prices from £178 to £924, a £746 spread on the same certified stone. Reve Diamonds lists it at £924. 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.
