About this 1.2ct natural cushion diamond

This 1.2ct natural cushion sits in the classic one-carat band, graded L colour (faint-tinted) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1559356750. Listed at 10 retailers as of November 6, 2026, with prices from £926 to £1,741, a £814 spread on the same certified stone. Yorxs lists it at £1,741. 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.
