About this 1.28ct lab-grown heart diamond

This 1.28ct 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 LG838640953 or 838640953. Listed at 11 retailers as of November 1, 2026, with prices from €199 to €1,186, a €987 spread on the same certified stone. Brilliant Earth lists it at €1,186. 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.
