About this 1.5ct natural cushion diamond

This 1.5ct natural cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2221285181. Listed at 19 retailers as of October 29, 2026, with prices from £7,812 to £13,974, a £6,162 spread on the same certified stone. MOH London lists it at £13,974. 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.
