About this 1.2ct natural cushion diamond

This 1.2ct natural cushion sits in the classic one-carat band, graded G 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 1553455695. Listed at 14 retailers as of October 28, 2026, with prices from £1,156 to £3,848, a £2,692 spread on the same certified stone. Queensmith lists it at £3,848. 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.
