About this 1.53ct natural cushion diamond

This 1.53ct natural cushion sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5526544058. Listed at 6 retailers as of November 2, 2026, with prices from £3,225 to £5,567, a £2,341 spread on the same certified stone. MOH London lists it at £5,567. 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.
