About this 1.03ct natural cushion diamond

This 1.03ct natural cushion sits in the classic one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5443466120. Listed at 15 retailers as of November 4, 2026, with prices from £1,106 to £2,301, a £1,195 spread on the same certified stone. MOH London lists it at £2,301. 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.
