About this 1.03ct natural cushion diamond

This 1.03ct natural cushion sits in the classic one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5233480600. Listed at 21 retailers as of November 4, 2026, with prices from £2,494 to £5,155, a £2,661 spread on the same certified stone. MOH London lists it at £5,155. 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.
