About this 1.04ct natural cushion diamond

This 1.04ct natural cushion sits in the classic one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2157240144. Listed at 5 retailers as of November 5, 2026, with prices from £1,792 to £2,108, a £316 spread on the same certified stone. Yorxs lists it at £2,108. 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.
