About this 1.26ct lab-grown heart diamond

This 1.26ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG841631841 or 841631841. Listed at 13 retailers as of November 4, 2026, with prices from £164 to £863, a £699 spread on the same certified stone. Reve Diamonds lists it at £863. 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.
