About this 1.22ct natural heart diamond

This 1.22ct natural heart sits in the classic one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2537303263. Listed at 14 retailers as of November 1, 2026, with prices from £1,918 to £3,954, a £2,036 spread on the same certified stone. MOH London lists it at £3,954. 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.
