About this 1.2ct lab-grown heart diamond

This 1.2ct lab-grown heart sits in the classic one-carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG674506577 or 674506577. Listed at 15 retailers as of November 6, 2026, with prices from £142 to £1,360, a £1,218 spread on the same certified stone. Do Amore Diamonds lists it at £1,360. 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.
