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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 6451465219. Listed at 8 retailers as of November 4, 2026, with prices from £852 to £1,443, a £592 spread on the same certified stone. Yorxs lists it at £1,443. 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.
