About this 1.25ct lab-grown heart diamond

This 1.25ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI. Listed at 3 retailers as of October 30, 2026, with prices from £364 to £863, a £499 spread on the same certified stone. Diamond Exchange Canada 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.
