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 1317031533. Listed at 9 retailers as of November 4, 2026, with prices from £1,004 to £2,172, a £1,168 spread on the same certified stone. MOH London lists it at £2,172. 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.
