About this 1.01ct lab-grown heart diamond

This 1.01ct lab-grown heart sits in the classic one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG436046507 or 436046507. Listed at 9 retailers as of November 5, 2026, with prices from £463 to £2,857, a £2,394 spread on the same certified stone. MOH London lists it at £2,857. 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.
