About this 1.03ct natural cushion diamond

This 1.03ct natural cushion sits in the classic one-carat band, graded G 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 6545048687. Listed at 9 retailers as of November 4, 2026, with prices from £1,310 to £2,826, a £1,516 spread on the same certified stone. MOH London lists it at £2,826. 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.
