About this 1.09ct lab-grown heart diamond

This 1.09ct lab-grown heart sits in the classic one-carat band, graded H colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG823696330 or 823696330. Listed at 19 retailers as of November 4, 2026, with prices from £135 to £797, a £662 spread on the same certified stone. Reve Diamonds lists it at £797. 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.
