About this 1.2ct natural radiant diamond

This 1.2ct natural radiant 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 2386328015. Listed at 5 retailers as of November 4, 2026, with prices from £2,808 to £5,322, a £2,514 spread on the same certified stone. MOH London lists it at £5,322. 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.
