About this 1.01ct natural cushion diamond

This 1.01ct natural cushion sits in the classic one-carat band, graded M colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI 533291472. Listed at 2 retailers as of November 3, 2026, with prices from £599 to £825, a £226 spread on the same certified stone. Yorxs lists it at £825. 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.
