This 1.26ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG745505059 or 745505059. Listed at 12 retailers as of October 30, 2026, with prices from £152 to £1,455, a £1,304 spread on the same certified stone. Do Amore Diamonds lists it at £1,455. 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.
