About this 1.08ct lab-grown heart diamond

This 1.08ct lab-grown heart sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG693546885 or 693546885. Listed at 14 retailers as of November 6, 2026, with prices from £134 to £843, a £709 spread on the same certified stone. Reve Diamonds lists it at £843. 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.
